In the summer of 1975, BS&T recorded a live album that was released in Europe and Japan the following year as "In Concert". This very same album was later released in the US as "Live and Improvised" in May 1991. The album featured different guitarists on different nights: Georg Wadenius, Steve Khan and Mike Stern, the latter who took over permanently for a time (Jeff Richman filled in for Stern in mid-1976). Jazz percussionist Don Alias was also present for the live album. After its recording, Joe Giorgianni left and was replaced by Forrest Buchtel (formerly of Woody Herman's band).
