Stephen Bruton was an immensely talented guitarist, singer and songwriter who was part of the Texas generation and milieu that produced Jimmie Dale Gilmore, Janis Joplin, Kris Kristofferson, Delbert McClinton and many other great musicians, including his close friend T-Bone Burnett, at whose house he died this morning. His music incorporated influences of blues, bluegrass, country, jazz, norteño and rockabilly.
The clip above shows him recording his song, "Getting Over You." This song was also recorded as a duet by Willie Nelson and Bonnie Raitt, and released on Willie's album Across the Borderline.
