Departures of note

David Surkamp was the lead singer and frontman of Pavlov's Dog, a progressive-rock band formed in St. Louis in the early 1970s. He was the band's principal songwriter and distinctive vocalist, known for his high, dramatic tenor voice. The band released its debut album, Pampered Menial, in 1975, which became a cult favorite among progressive-rock fans. Although Pavlov's Dog never achieved the arena-filling success of contemporaries like Yes or Genesis, the band maintained a devoted following and continued to perform and record over the decades, with Surkamp as its enduring centerpiece. He died at age 73.
