 A second LP, "Medium" was completed in early 1969 to similar high acclaim.Kac (and his Rock-Si-Chord) left the band following "Medium," citing musical differences, and in the summer of 1969 the remaining trio traveled to England to record a live-in-the-studio acoustic album with famed producer Shel Talmy.Booked to tour the U.K. with Todd Rundgren's new band The Nazz, unfortunately an English union disagreement prevented any American musicians from performing that summer.
