CineCalidad. Doyle Bramhall II, Charlie Sexton and Chris Layton and Tommy Shannon from Stevie Ray Vaughan's band Double Trouble formed the Arc Angels in the early 1990s. This once-in-a-lifetime concert reunites the quartet at the historic Alamo. The group plays the highlights from their self-titled (and only) album for the first time in more than 10 years. They also discuss the band's history and their ties to the late great Vaughan in an exclusive interview.
