Together with recordings by Otis Rush and Buddy Guy (also Cobra artists), the West Side Sound was a manifesto for a new kind of blues.[6] He continued performing live and toured with a band that included blues harp player Charlie Musselwhite, future Commander Cody and His Lost Planet Airmen bassist "Buffalo" Bruce Barlow and drummer Sam Lay.[9] In February 1970, the Butterfield Blues Band played at a benefit concert for Magic Sam, at Fillmore West in San Francisco.Author Stephen Thomas Erlewine writes: He [Magic Sam] not only makes "Sweet Home Chicago" his own (no version before or since is as definitive as this), he creates the soul-injected, high-voltage modern blues sound that everybody has emulated and nobody has topped in the years since.[11]For the performance of the song in the 1980 film The Blues Brothers,[12] John Belushi's character announces, "dedicate[d] to the late great Magic Sam".
