It’s kind of a shame that Jeff Coffin’s career is going so well. I mean, I don’t begrudge him the nice livelihood that he’s earned as a longtime sideman with Béla Fleck and, in recent years, The Dave Matthews Band — but frankly, for purely selfish reasons of my own musical taste, I’d be eager to see what would happen if the Nashville saxophone stalwart and his ever-evolving Mu’tet became a full-time gig. After listening to their latest recording, Jeff Coffin & the Mu’tet Live!, it seems obvious the same crowd that packs clubs for Medeski Martin & Wood, John Scofield, Charlie Hunter and the like — basically, the common ground where jazz fans and jam-band fans overlap — would be packing the clubs for Coffin. Propelled by one of the most explosive rhythm sections you’ll ever hear — drummer Jeff Sipe and bassist Felix Pastorius — the two-disc set features terrific compositions and fearless improvising. If you miss the late jazz giant Michael Brecker, hard-grooving jazz-funk workouts like “Tag” and “The Evil Boweevil” will bring a smile to your face. Despite its French-sounding title, the entrancing “L’Esperance” hints more at Latin and Middle Eastern sounds. And no Coffin outing is complete without some greasy Crescent City grooves, here represented on “Move Your Rug” and also the loosey-goosey “Tall & Lanky,” which features some of Pastorius’ finest moments. (Pastorius is clearly his own man, but it’s impossible not to hear the DNA of his late, legendary bass-playing father bubbling to the surface at times, in an almost eerie way.) Other noteworthy performances come from trumpeter Bill Fanning and Nashville keyboardist Chris Walters, who has a fabulous new album of his own, Yay! Everbody Yay!
