San Antonio’s Michael Guerra is a young but experienced accordionist who has the best Texas music has to offer: that rootsy, bluesy mix of rock and Americana. Whether solo, with The Mavericks, or playing alongside other Lone Star greats, Guerra is the type of artist unafraid of making quality music palatable for all without sacrificing edge. The best thing about his 2012 self-titled CD (which includes five of his own fine songs), are three gems: The Krayolas’ Héctor Saldaña’s “My Love’s Too Big” (especially written for him), a rockin’ Tex-Mex version of The Who’s “Squeeze Box,” and a beautiful bolero version of Roberto Cantoral’s “La barca.” Guerra has a pleasant voice and he gets by, but this is about his accordion, his band, and his songs, and I’m perfectly fine with that.
