As the heart and soul of ZZ Top, Billy Gibbons has made a prolific stock-and-trade out of powerhouse riffage and throw-down boogie rock, and yet, somehow, in all this time, he’s never come out with a solo record. As the story behind Perfectamundo goes, it was sparked by an invitation that Gibbons received in 2014 to play the Havana Jazz Festival; he couldn’t make the gig, but he was moved by the possibilities and jumped into building tracks for a collaborative studio project with an Afro-Cuban flavor. Of course, Gibbons is a Texas bluesman first and foremost, so “You’re What’s Happenin’, Baby” (with such patented Gibbons musings as “You’re a fine little honey with your shorty shorts on”) opens with a buzzing Dobro filigree before it launches into a groovy ZZ strut, buttressed by keyboard guru Mike Flanigin’s tasty B3 organ solo and Gibbons’ own sweetly distorted guitar whistles. “Sal Y Pimiento” goes all-in—a bit more Tex-Mex than honest-to-Habana-Vieja, but Martin Guigui’s percussive acoustic piano and Flanigin’s B3 lines keep the rumba rhythm churning. True to form, Gibbons’ gargled-sawdust vocals and exceedingly laid-back, nudge-wink delivery lend just the right sense of cool to songs like the upbeat, Auto-Tuned “Hombre Sin Nombre” and the hilarious “Quiero Mas Dinero.” It’s not exactly rocket science, but it rocks.
