He" invented the technique of `slip-cueing': holding the disc with his thumb whilst the turntable whirled beneath, insulated by a felt pad. He'd locate with an earphone the best spot to make the splice, then release the next side precisely on the beat...His tour de force was playing two records simultaneously for as long as two minutes at a stretch. He would super the drum break of 'I'm a Man' over the orgasmic moans of Led Zeppelin's `Whole Lotta Love' to make a powerfully erotic mix...That anticipated the formula of bass drum beats and love cries...now one of the cliches of the disco mix." (Referring to DJ Francis Grosso at the Salvation club in New York in the mid-seventies, from Disco by Albert Goldman. Also referred to in "Behind the Groove," by Steven Harvey, in Collusion #5.
