Nelson found the structure of a permanent band constricting. An instrumental on "Drastic Plastic" performed by Nelson (acoustic guitar) and Clark (keyboards) anticipated Nelson's later solo ambient work. Other tracks on that album required Fox record drum parts for use as repeating loop backing tracks in the studio. (Performing these songs live on the subsequent tour, Fox would physically play these repeating patterns on drums). This sowed the seeds for later experimentation by Nelson. 1983's "Invisibility Exhibition" tour would see Bill Nelson (guitar) and Ian Nelson (sax) improvise to the former's self-produced backing audio (and video) tracks (later released as the "Chamber of Dreams" album), an approach Nelson would repeat for many solo live performances throughout his career. Playing the guitar over pre-recorded backing tracks would bear further fruit in later studio recordings, notably the "Painting With Guitars" series (2003, 2015) and "And We Fell into A Dream" (2007).
