The first record of the C.S. series was issued in 1980 and the last one in 1984. The serie consists of 1 official and 15 bootleg records. All records were pressed in Germany. Due to safety reasons the label-design changed dramatically over the years. C.S. stands for the two people who founded the label. All the mixes are quality mixes and the first parts are copied from the Disconet records. The first 8 parts were mixed by mainly Dutch mixers. After that most of the mixes were made in Germany by one of the founders of the label.
