SRV breaks out of the gate with Little Stevie Vaughan before he was Stevie Ray. A member of Paul Ray and the Cobras, the kid’s doing “Thunderbird”—the upbeat, swinging standard by the Nightcaps, Texas’ first great white-boy blues band—a song that every Dallas kid with an electric guitar and an attitude knew by heart. The voice is already full-formed, deep and bluesy. The instrumental prowess, in terms of tone, technique, and attack, is already over the heads of his bandmates. And so begins a long evolution, detailed by the low-down and dirty reading of “I’m Crying,” from Vaughan’s first recording session with Double Trouble, followed by a full-throttle shuffle, “You’re Gonna Miss Me Baby” and 51 other tracks. Most of the songs on this three- CD set are unissued alternate studio takes or live performances. Rarer gems like “Rude Mood/Pipeline” performed with brother Jimmie for MTV and three songs from Vaughan’s last gig, at Wisconsin’s Alpine Valley, are worth the price of admission alone. Taken as a whole, it is even better—a remarkable body of work. So if earlier recordings Vaughan made as half of Blackbird with Christian-Charles de Plique or as part of the Nightcrawlers with Doyle Bramhall and Marc Benno in the early seventies are missing (or even “Let’s Dance,” the song and guitar break that made David Bowie’s career), it’s a minor complaint. What’s important is that the box set captures Stevie Ray Vaughan in full blazing glory, locked into that sweet spot where he could soak up roots, tradition, and soul the way he did so well and then take all that to the next level. Ten years after he died, it’s clearer than ever: SRV was in a different zone. Texas guitar will never sound the same.
