Alan Iglesias and Crossfire is the best Stevie Ray Vaughn tribute band you are likely to hear, but the band’s appeal is much broader than that. Appearing at Tio Leo’s on May 3, the trio replicates Vaughn’s sound amazingly well, and Iglesias has a more-than-passing resemblance to Vaughn, even dressing the part. So fans of the late guitarist will love every second of the show. However, if you just like blues music or stellar guitar playing, this performance works. The set includes numerous standards, and Iglesias’ fretwork skills are impressive, so it’s easy to imagine you are really listening to Vaughn. Few tribute acts sound this close to the real thing. • ALAN IGLESIAS AND CROSSFIRE: Saturday, May 3 at TIO LEO’S, 5302 Napa St. 9 p.m. 21 and up. Cover TBD. www.tioleos.com.
