Douglas Wayne Sahm (November 6, 1941 – November 18, 1999) was an American musician, singer-songwriter, and multi-instrumentalist from San Antonio, Texas. He is regarded as a key Tex-Mex music and Texan Music performer. San Antonio's conjunto and blues and later the hippie scene of San Francisco helped create his blend of music, with which he found success performing in 1970s Austin, Texas.
He made his recording debut as "Little Doug" in 1955. In 1965, Huey P. Meaux produced Sahm and the Sir Douglas Quintet's "She's About a Mover." Atlantic Records signed Sahm and released his debut solo album Doug Sahm and Band in 1973. In 1989, Sahm formed the supergroup the Texas Tornados with fellow Tex-Mex musicians Augie Meyers, Freddy Fender and Flaco Jiménez. The Texas Tornados toured successfully, and one of their releases earned a Grammy Award. In 1999, Sahm died during a vacation trip.
