Mescalero ZZ Top

Ever since ZZ Top signed with RCA, they fitfully tried to break free of the synthesized blues that once was their savior but quickly became a straitjacket. Like any addict, it was hard for them to quit that processed, sequenced sound cold turkey, so they weaned themselves off the robo-boogie, sometimes relapsing and adding too many synths to mix, other times breaking loose with some credible boogie. Apart from the dreadful misstep of 1999's XXX, they showed signs of life on all their RCA albums, and their fourth, 2003's long-delayed Mescalero, is no exception to the rule. Billy Gibbons' fat guitar tone really has some presence here, at least on some of the album, and there are enough rhythm tracks not performed to a didactic click track to provide some real swing.

Following 2004's Rancho Texicano: The Very Best of ZZ Top by a decade, The Very Baddest of ZZ Top comes in two different styles: a single-disc compilation with 20 tracks and a set that doubles it. The single disc is good, racking up most of the MTV-era hits – "Gimme All Your Lovin," "Sharp Dressed Man," "Legs," "Got Me Under Pressure," "Rough Boy," "Velcro Fly" – while doubling back for "La Grange, "Tush," "I Thank You," "Waitin' for the Bus," "Jesus Just Left Chicago," "I'm Bad, I'm Nationwide," and "Cheap Sunglasses." It's enough to satisfy the very casual fan, but even a quick glance at the track listing reveals plenty of missing favorites: no "Pearl Necklace," "I Heard It on the X," "It's Only Love," "Francine," "Just Got Paid," and "Sleeping Bag."
