is a bad ass. He wears big black sunglasses on stage and plays a swaggering brand of rock 'n' roll that embraces the genre in all its fullness. Which means his music can sound punked-up here, honky-tonked there and '60s-era guitar pop-y everywhere else. He's earned the right to wander. In the '70s, he played guitar with the Nuns, a seminal San Francisco punk act that opened for the Sex Pistols at their final concert. In the '80s, he returned to his home state of Texas, where he spent time leading alt-country bands like Rank and File and the True Believers. Since the '90s, he's released a steady stream of acclaimed solo albums (No Depression named him its artist of the '90s), each one more appreciated than the one before. Especially lately. Escovedo's latest albums, “The Boxing Mirror” and “Real Animal” (produced by legends John Cale and Tony Visconti, respectively) might be the best (and best-received) of his career.
