ZZ Top – El Loco. Includes ONLY SIDE 2 of the direct metal master (DMM) for the album. The DMM is used to create the stampers (an inversion of the record) that the vinyl gets pressed onto. Each side of the album is a single DMM, so this piece is just for Side 2. The DMM features the matrix/run-out. BSK-2-3593-RE 2-S3 MASTERDISK RL + SLM ++. The Allied Record Company was a pressing plant in Los Angeles. The DMM does have a scratches and surface marks (as well as some fogging). This is more a collectible and not something you would expect to be able to play at home. But these are not easily found outside pressing plants and for those who collect, this is a great find. Photos are of actual items.
