Texas Flood was the thunderclap from a clear blue sky. The album appeared in midsummer 1983, when most saw blues-rock as a quaint remnant of rock's past, introducing the power trio Stevie Ray Vaughan and Double Trouble to an unexpecting world. Its raw crunch and confident swagger was undeniable. For rockers, Texas Flood had the right volume and drive; for blues purists,it dignified the tradition. For those seeking an anarchic, punk-like rush, it felt like a roaring, rattling train about to skip its tracks.For all, the album unveiled a new guitar genius who would come to show that much remained to be written in the book on electric guitar. The original ten tracks of Texas Flood plus a never released concert performance by Stevie Ray and Double Trouble from Philadelphia that same summer comprise this special 2-CD, 30th anniversary collection.
