Happy Trails is the 1969 follow-up to Quicksilver Messenger Service's self-titled folk-rock inflected debut. Largely recorded live in concert, the album opens with a 25 minute, six-part suite of Bo Diddley's "Who Do You Love" and is anchored with a version of his song "Mono." One of the first releases to successfully capture the San Francisco sound, Happy Trails displays Q.M.S. as true pioneers of extended improvisation in the live setting.
