Details: It's been a half century since Pavlov's Dog burst onto the burgeoning progressive rock scene of the early 1970s. Hailing from the city of St. Louis, Missouri, their heady blend of rock, classical and folk music turned them into cult legends. The band has seen lots of lineup changes and internal turmoil over the years, leading to extended breaks between album releases. But today, David Surkamp - lead singer, main songwriter and last remaining original member of Pavlov's Dog - continues to fly the banner high, accompanied by an accomplished group of musicians that is a credit to the band's good name. For decades, Pavlov's Dog's "lost album" - "Has Anyone Here Seen Siegfried?" - recorded in St. Louis in 1977 - was available only in inferior quality. With the rediscovery of the master tapes several years ago, it became possible to hear the album as originally intended. Tensions within the band had reached the boiling point as they entered the studio and would lead to a breakup soon thereafter. Nevertheless, tracks like the piano ballad "Only You" and the somber "Suicide" are brilliant additions to the band's canon.
