In 1988, they released the album "Clear Black Paper" on Sub Pop. They were the first non-Seattle band to sign to the record label. According to Mark Arm, Glitterhouse and Sub Pop had formed an agreement. Glitterhouse wanted to release a Green River record in Germany, and the labels did a swap: Green River for the Fluid. In the same oral history, Greg Prato's "Grunge Is Dead", musician Rod Moody said that the Fluid sounded like no other band on the Sub Pop roster.
