Sir Doug & The Genuine Texas Cosmic Groove tells the story of Doug Sahm, the wild man musicians’ musician and unsung hero of Texas music. A country music child prodigy and teenage rhythm & blues dynamo who caused a riot at his San Antonio high school, Sahm emerged as an international rock star leading the Sir Douglas Quintet. He landed in San Francisco just in time for the Summer of Love in 1967. He returned to Texas as the cowboy hippie rocker who built a burgeoning music scene in Austin in before forming the Tex-Mex super group The Texas Tornados. A kinetic, quirky character with a solid sense of place as well as an innate wanderlust, Doug Sahm’s story is the story of Texas music.
