This fun-loving group has been around since 1977, and that’s a good thing. Rooted in New Orleans' venerable brass-band tradition, Dirty Dozen have never let themselves be hemmed in by playing only one style. Funk rhythms abound, saxophonists aren’t afraid to squeal and scream like free-jazz players, and guitarist Jake Eckert rocks out. There’s even a strikingly inventive cover of Rihanna’s 2007 hit single “Don’t Stop the Music.” The funky opener, “Tomorrow,” is warmed up by guest Nigel Hall’s Hammond B3 organ and a husky solo from baritone saxophonist Roger Lewis. Sousaphone player Kirk Joseph’s “Jook” evokes tough '60s soul-jazz, as well as other genres. The band doesn’t turn its back on New Orleans traditions; the album includes a take on “When the Saints Go Marching In,” as well as a jump-blues arrangement of the traditional “E-Flat Blues,” complete with shouts of “Hey!” The album closes on a high note with Lewis’ hard-partying “Dirty Old Man.” Lewis—who at age 70 is the group’s senior member—turns in a performance that'll bring a smile to your face.
