When Stevie Ray Vaughan and Double Trouble welcomed  Jimmie Vaughan to join them on stage April 15, 1984 at the Austin Opera House to help them perform “Cold Shot“, Stevie’s big brother was actually a bigger star then by virtue of anchoring the butt-rocking guitar slot in the Fabulous Thunderbirds. Younger sibling Stevie’s second album, Couldn’t Stand the Weather , had just been released and the good-natured rivalry between to the two bands over the next six years would lead a major musical Texas renaissance that was magic to behold. –Redbeard
