    Thread to discuss my intention for identifying and crediting English disc manufacturing plant DiskXpress based on mould SID code and sequential matrix number

    Diskxpress - manufacturer which ran a plant in Gloucestershire (I'm unsure when the plant started and ended operations)

    ### Credited on mid-1990s CDs by DISKXPRESS in the disc matrix.
    Examples:
    Various - Platipus Records Volume Two
    These CDs have no SID codes, so it's hard to pin down where they may have been glass mastered, but possibly replicated by DiskXpress

    ### Around 1998, a 5-digit matrix number NNNNN and mould SID code IFPI 8Y** began appearing.

    -> A small number of such discs exist that name DISKXPRESS in full in the matrix: Saddar Bazaar - Path Of The Rose

    -> A larger number instead use the initialism 'DXP' in the matrix: https://www.discogs.sie.com/search/?q=%22ifpi8y%22+%22dxp%22&type=release

    -> And probably an even larger number don't directly refer to DiskXpress at all in the matrix

    ### It seems likely that DiskXpress never did in-house glass mastering - glass masters that I've come across with 8Y** include Independent Masters Ltd. The matrix will usually include the initial of the glass master origin (N, E, FT, I respectively).

    ### From the few releases with matrix numbers linked in LCCN so far, the NNNNN number appears to be sequential and chronological. Here's a 2CD release with almost directly sequential numbering: Various - Trancentral Eight

    The NNNNN number is also present in combination with IFPI 8Y** +/- DXP across all 4 different glass master origins. Saddar Bazaar - Path Of The Rose is a good example.

    Matrix / Runout (Variant 1): DISKXPRESS 00470 DELECCD068 SPFT 11095/1031898
    Mastering SID Code (Variant 1): none
    Mould SID Code (Variant 1): ifpi 8Y03
    Matrix / Runout (Variant 2 - Mirrored): AAC2312 00470 DELECCD068SP •
    Matrix / Runout (Variant 2 - Additional Moulded): 1 : 0
    Mastering SID Code (Variant 2 - Mirrored): IFPI L123
    Mould SID Code (Variant 2): ifpi 8Y07

    CONCLUSION

    (1) Given that we know that DiskXpress ran its own manufacturing plant, and that its name or initialism co-occurs with IFPI 8Y** on several dozen releases so far, I think it should be fair to make the association between the two.
    (2) Given that NNNNN is a release-specific number that accompanies IFPI 8Y** across different glass master variants, I believe it is worthy to be entered in LCCN
    (3) When DISKXPRESS or DXP is not found in the matrix, the combination of NNNNN and IFPI 8Y** should be sufficient to assign a Pressed By entry for DiskXpress

    I agree. This is what it looks like. In such cases I can suggest in the main profile FSV.

    E.g.:
    Emperor (2) - IX Equilibrium
    Made By - Forward Technology
    Manufactured By - FSV - 14191
    Pressed By - Diskxpress - 02217
    Matrix / Runout (Variant 1): DISKXPRESS 02217 CANDLE035CD FT 14191/1 012199
    Mould SID Code (Variant 1): ifpi 8Y01
    ...

    Manufactured By - Due to the lack of mastering SID code.
    I am convinced that the FSV did the matrix, but from experience I know that the role of "Glass Mastered At" will be difficult to get without the SID code.

    The IFPI 8Y** mould SIDs disappear after 2004:

    https://www.discogs.sie.com/search/?sort=year%2Cdesc&q=ifpi8y&type=release&format_exact=CD&layout=med

    However, the last matrix number seems to be for a 2002 release: 137

    What do we do with IFPI 8Y** CDs made in the remaining couple of years? Do we credits Diskxpress? Do we split from CDs with different mould SIDs?

    I would say we shouldn't credit Diskxpress, and we shouldn't split. Probably Diskxpress went out of business around 2002 and its machines were sold to a new plant. I've seen IFPI 8Y** variants on CDs manufactured by Lynic and by MPO Broadcrest, so I'd say most likely one of both of those plants acquired CD lines from Diskxpress.

    We should only credit Diskxpress by the combination of its NNNNN matrix number AND the mould SID code. Not by the mould SID alone, and especially not when Lynic or MPO Broadcrest is indicated by other matrix information.

    Also added a line to describe SP = Sound Performance and that the SP is often squashed together with the glass master ID - SPE, SPN, etc.

    I made diagrams of these numbers, you'll find them on my profile page. They do not look sequential. Given the fast turnover times in CD business I think it is pretty unlikely that a number range primarly used in one year will be used two years later.

    They are not out of sequence. The Diskxpress matrix number sequence would reflect the sequence in which orders were made by labels for manufacturing by Diskxpress. That doesn't always translate into the same sequence of release dates as some releases are delayed, mispressed, etc. I won't address all 6 examples, but the following explanation can apply to all of them:
    dborap
    Shadowland (2) - Ring Of Roses
    LCCN number: 00929
    Release Year 1997

    This could in fact be a second pressing of the album released in 1998, and the first pressing has different matrix info. Or it could be that the release date 1997 is incorrect. Or it could be that it was released in December 1997 and the "surrounding releases" were released in January 1998. And so on.

    What are you trying to say here? Do you doubt that the combination of 5-digit matrix number + IFPI 8Y** +/- DXP/DISKXPRESS is sufficient to identify these discs as Disxpress pressings? Or something else?

    The only one I could find is 641 Green Lanes, London., N8 0RE. https://find-and-update.company-information.service.gov.uk/company/01786191/filing-history
    It looks as if the company had liquidity problems from 1995 onwards and operations might have exceeded in 1997.
    There are a few releases from 1998 and 1999 credited with Diskxpress in the matrix, so the actual closing date might have been in 1999.

    CD manufacturers having problems with delays is true since about 2018
    https://www.billboard.com/music/music-news/cds-out-of-stock-manufacturing-moved-mexico-eminem-lil-wayne-8483294/
    “A year ago, you could order CDs to be manufactured and get them delivered in two or three weeks, and if you had a hot title, you could get a quick [turnaround] within one week,” says a sales executive. “Today, CD manufacturing now requires four to eight weeks of lead time, while the quick turnaround on a hot title now takes at least 10 days.”

    There are ~1000 releases linked on the Diskxpress profile currently with a pretty obvious sequential nature to the matrix numbers. 5#### was used briefly at first, then 0#### after that, starting with 000## in 1996 and ascending up to 07### in 2001. If you can't see the sequential nature in this then I don't think you understand what sequential means.

    These are interesting examples. It could be errors by the plant in asg numbers, or something else. In any case, these four releases make up 0.4% of releases on the Diskxpress profile so far. Does an 0.4% error rate invalidate a sequential numbering scheme?

    Could be a typo, do you have the CD to check the matrix? Ask someone to otherwise, preferably the submitter of the matrix data.

    Six releases are out of sequence.
    Unknown Artist - Pan Pipes Play The Music Of The Beatles
    LCCN number: 00080
    Release Year: 1999
    surrounding numbers were released in 1996

    Same label released it also in 1996, reissues frequently re-use glass masters or internal numbers.

    dborap
    Largeman - Plaything / Newboy
    LCCN number: 00347
    Release Year: 1999
    surrounding numbers were released in 1998


    When did it come out? Images shows no year and submitter shows no source for the date. This is an unsourced date to me.

    dborap
    Shadowland (2) - Ring Of Roses
    LCCN number: 00929
    Release Year 1997
    surrounding numbers were released in 1998


    It has a copyright of 1997. The release date guidelines are clear about this. In absence of other information it is the date do use. You don't go and put 1988 on a release with SID Codes? or a release made by EDC do you if the copyright says 1988? Correct?

    dborap
    Unknown Artist - 21 Songs, Stories & Nursery Rhymes
    LCCN number: 00939
    Release Year: 1999
    surrounding numbers were released in 1998

    No years visible on scan. The catalog number allocated for this release is lower than catalog numbers assigned 1998 on the label.

    Mr. Vegas - Heads High
    LCCN number: 02898
    Release Year: 1998
    surrounding numbers were released in 1999


    Copyright is 1998. Last release on CD by the label before copyrights start saying 1999. When exactly did this come out?

    Two releases are assigned to Diskxpress, but the Matrix looks different and does not actually contain ‘DXP’.
    Nathan McCree - Tomb Raider
    Matrix: 2:2 00163 TOMBRENG dXPE
    J.J. Burnel - Euroman Cometh
    Matrix: AAC1481 00561 EW0002CDDXP

    English is not my first language. What I meant was these two releases do not exactly credit DXP, but dXPE and CDDXP instead which could be something different.

    Nathan McCree - Tomb Raider has no mould SID code, but the pattern to identify Diskxpress is a supposedly sequential number + mould SID?

    So sequential means in your example:

    Yes. >90% of the items in that list are sequential. Others are explained by errors, typos, later pressings, and delayed releases, all of which has already been explained to you.

    Warepire has given you some good examples of the fact that you cannot ever trust a release date on a Discogs submission unless you have a verifiable primary source in the submission history.

    'DXPE' in the matrix of that submission is a combination of 'DXP' (the pressing plant) and 'E' which refers to EMI Swindon who manufactured the glass master. The Diskxpress profile has a section explaining the use of letters to identify the glass master origin

    dborap a small number of outliers in datasets don't invalidate conclusions drawn from the great majority of the data. They are statistically exceptions that prove the rule.

    These outliers are more in the nature of data 'UFO's' and having identified them the next step is not to conclude that the conclusions are wrong/invalid, as you appear to be doing, but to try and find a reasonable explanation for what may have caused these outliers to be there.

    And, as you have seen from the responses there are plenty of reasonable explanations.
