    Legendary mastering studio where releases by many Detroit techno artists where mastered, cut and engineered.
    In 1989 Steve Martel and Ron Murphy decided to open a store specializing in old phonograph records, situated at 17610 W. Warren in Detroit, Michigan called National Sound Corporation. Ron Murhpy had been mastering records since the mid 1960's for recording artists such as Isaac Hayes and Forest Hairston.

    When forming National Sound Corporation, Ron and Steve had the idea of also being able to cut Dub plates and records for use in their customer's jukeboxes, and so some record cutting equipment was also set up in one of the shops back rooms. Shortly after opening, they were visited by Derrick May and Juan Atkins who, while looking for records, noticed the cutting lathe and asked about having some acetates made. After cutting a couple of dubs for Derrick and Juan, Ron was told that there were a lot of Detroit producers that needed a local place to have dubs and masters cut. Ron decided to upgrade the equipment while Derrick and Juan spread the word about the new cutting service.

    The first master to be cut was Plus 8 Records Ltd. label, followed a week later by Underground Resistance label. Since those first masters back in '89 there have been thousands that have followed, all inscribed with the initials NSC. Producers were encouraged by Ron to make their records unique, by including information and phrases written onto the records, and even going as far as to talking Kevin Saunderson into cutting one of his records in reverse, and cutting locked grooves for Jeff Mills' Discovers The Rings Of Saturn project.

    The death of Steve Martel in 1994, and the subsequent problems that arose with the remaining estate, led Ron to purchase the equipment and relocate the recording service to a new location, the success of which had already led to the closure of the retail side of the business. The new name chosen was the Sound Enterprises, however Ron continued to put the old NSC logo on each master produced, in memory of Steve Martel without whom the business would have never been started.

    Sadly, Ron Murphy passed away on Saturday, January 12th 2008.

    French pressing plant, manufacturing and distribution company which stemmed from their original pressing plant in Averton (Mayenne), France, established by Pierre Tyrel de Poix in 1957. The 'MPO' acronym remains from the original company; 'Moulages et Plastiques de l'Ouest'. Through expansion, MPO has permanent offices throughout the world, with a strong presence in Europe. The group's operations are structured around its three production sites and logistics centres; MPO Iberica and MPO France (Averton and Villaines La Juhel) and MPO Asia (Bangkok, Thailand) and numerous sales offices in Europe and Asia as well as a partner in the US.

    MPO is an acronym for "Moulages Plastiques de l'Ouest" (in English: Western Plastics Castings).

    MPO pressed its first commercial CD on 4th of December, 1984.

    Vinyl discs pressed by MPO usually have the hand etched "MPO" inscription in the runouts.
    Recent presses could also show a stamped logo followed by a string of digits ## ##### (see this image), where the first two digits stands for the pressing year.
    Another identifier can be that MPO pressings have three concentric rings around the spindle hole (see this image).
    MPO can be credited as M.P.O. on releases.

    On cassettes: "Duplication MPO", most often printed on labels.

    MPO CDs made at Averton are assigned the following SID codes:
    Mastering: L031, L032, L033, L035, L036, L039, LY88 (often misread as LV88)
    Mould: 12##

    MPO isn't always explicitly mentioned in the CD matrix, but can sometimes be identified by a string of tiny text with the following format:
    CA [label cat#] [one or more @] IFPI [mastering SID code] M/D/YYYY HH:MM:SS [AM/PM] NNNNNNNNNN
    (This isn't usually allowed, but there was forum discussion for doing this for MPO in particular.) If you aren't sure, please ask in the forums.)

    CD matrix was stored for 2 years, i.e. any represses in that time window will bear the same number.
    If the original CD matrix became damaged, a new one was created with a new number.

  5. P.R. Records Limited

    P.R. Records Limited
    Vinyl pressing company founded by Phil Race in February 1979. Vinyl production started October 1979.

    Records pressed at P.R. are identifiable by a combination of the unique stamper ring impressions AND a PR- type etching in the matrix/runout (plus an additional letter denoting the Metalworker).
    Examples: PR-E, PR-M, PR-M, PR-R, PR-CED, PR-CD, PR-G, PR-P & PR-T.

    Some records, however, were pressed at different pressing plants using masters (metal parts) prepared at P.R. Records Limited. In such cases the etchings will be present but there will be different stamper ring impressions in the label area around the center hole.

    Peter Lawrence aka PAG worked there.

    Disctec, a sister company for CD production, opened in 1986.

    End of the 1980s or in the early 1990s, CM Records acquired a majority stake in PR Records and control was handed over to the new owners (which already had individual stakes in PR Records), Neil Sharpley and David Bulmer.

    Neil Sharpley and Robert Bulmer (David Bulmer's son) still run the company. More
