This weekend, Austin City Limits, the long running PBS series, puts the spotlight on performances Stevie Ray Vaughan and Double Trouble did on show before his tragic death. Stevie Ray Vaughan: 30 Years On marks the 30th anniversary of the post concert helicopter crash in 1990 that claimed the life of the Lone Star state guitar legend at age 35.  Stevie Ray's brother Jimmy Vaughn said ACL filmed some of Stevie's best performances.  Anyone lucky enough to catch him in concert during his all too short career can attest t

o his jaw-dropping greatness, so this special should indeed be special. Here's a taste of what's in store.
