The "core group" Mick, Jim, Joey, and Paul will work out a new songs primary structure. Then in rehershal extras like percussion, DJ beats, and samples are added where needed. Sometimes songs developed in the couse of jamming or fooling around with a riff. Eyeless started with a beat Sid was kicking out from his turntables, Mick started playing the little noise line, and soon the song was written. ONCE THE MUSIC IS COMPLETED, Corey works on lyrics.
