Unison is the first album of Japanese composer

Bill Laswell, avant-garde guitarists
Buckethead (who would join
Guns N' Roses soon after the recording sessions) and

Parliament-Funkadelic keyboardist
Bernie Worrell. The album met very good reviews from critics mainly because of the soft guitars and the funky bass.[2]
