GM Records was a Polish label and manufacturer, established by Marek Grela and operated between 1st of June 1990 and 16th of August 2017.

Originally a pirate cassette label and duplicator, GM Records later branched into CD and DVD replication. Related services were also offered and included the usual authoring, premastering and mastering services. They commenced pressing vinyl records in December 2015.

Effective 17 August 2017, GM Records was sold and the plant continued to operate as wmfono, which was acquired in 2021 by XDiSC.

CD Identification
The matrix number scheme is dd######mm, where
dd is the date of the glass mastering day (01 - 31),
###### is a 6 digit matrix number (where # can be 0 to 9 - started with 000 001)
mm identifies the glass mastering month (01 - 12).

Example: 0408331504 was glass mastered on 04 April; 1908353809 on 19 September.
Note: The release year cannot be derived from the matrix number alone.

When trying to credit the correct name of this plant on 2017 releases, the dd and mm glass mastering date in the matrix number can help direct you - any date before 17/08 belongs to GM Records; any date after that day belongs to wmfono.

When entering GM Records matrix numbers into LCCN, the full dd######mm part of the string should be entered. An example of how to correctly credit GM Records can be found on Amenra - Alive.

Mastering SID Codes: IFPI T57 (first old version without letter L), IFPI LT57 and IFPI LT 58.

Note: Often the matrix also shows "Monotype Rec" - Monotype Records or "Monotype Pressing". This identifies the broker who ordered the pressing and should be credited as Manufactured By only.
