Double Trouble is an American blues rock band from Austin, Texas, formed by guitarist/singer Stevie Ray Vaughan in 1978. The group was active throughout the 1980s and contributed to reviving the blues, inspiring many later blues and rock musicians. Formed in Austin, Texas, by 1985 the group consisted of Vaughan, Chris Layton (drums), Tommy Shannon (bass), and eventually Reese Wynans (keyboards). While with Vaughan the band was billed Stevie Ray Vaughan and Double Trouble. Rooted in blues and rock music, the group worked in many genres ranging from ballads to soul, often incorporating jazz and other elements.
Initially a five-piece lineup with Vaughan, Lou Ann Barton (vocals), Fredde Walden (drums), Jackie Newhouse (bass) and Johnny Reno (saxophone), they built their reputation playing clubs around Texas over a four-year period. Molded into a trio (Vaughan, Layton, Shannon), their musical potential was encouraged by producer John H. Hammond, who got the band a recording contract with Epic Records. They gained popularity after their debut album, Texas Flood, became a critical and commercial success in 1983. By the mid-1980s, they had become an international act, touring extensively around the world until August 1990, when Vaughan was killed in a helicopter crash after departing East Troy, Wisconsin.
Various posthumous releases featuring Vaughan have been issued since his death, overseen by his brother Jimmie. Since Vaughan's death, Double Trouble has continued in various capacities, releasing a studio album in 2001 and acting as a session band for blues and local Austin musicians. The band has sold over 11.5 million albums in the United States, receiving platinum certifications for all four of their studio albums featuring Vaughan. They have won four Grammy Awards including Best Contemporary Blues Performance for their album In Step (1989).
Layton & Shannon have also released a number of albums as Double Trouble, as well as being the rhythm section of the band  Arc Angles.
