The M-Shop got a good dose of southern-style booty shakin’ jazz Thursday, from one of the most prolific bands on the New Orleans jazz scene — The Dirty Dozen Brass Band.

The group has been around for nearly 20 years making quite a stir with their funky and groove-oriented charts, with a somewhat eclectic mix of instruments, including a sousaphone.

Led by the drums and sousaphone picking up the bass line, the rhythm section laid down such a hard, straight-ahead groove it’s a sin not to dance to, as evidenced by the enthusiastic audience response at Thursday’s show.

The frontman set it all in motion by asking if it was always “That quiet in here?” The band then followed with a loud and funky opening number.

The seven-piece group had plenty of sound to offer at the small M-Shop, creating a party atmosphere to which the crowd responded to favorably. It was quite possibly the Shop’s loudest and most energetic crowd yet this year, as a dance floor was cleared in the back and booty shakin’ ran rampant.

Each musician equally aided in creating the full, authentic sound of New Orleans demonstrating immense skill. The band also created some far-out sounds, such as the saxophonist playing a baritone and soprano simultaneously and the sousaphone playing somewhere up in the trumpet range.

They played several crowd favorites such as a funky “When the Saints go Marching In,” which contained an impressive number of solos, and the Duke Ellington standard, “Caravan,” with a very strong back-beat feel.

Their latest album, “Buck Jump,” was produced by the notable John Medeski of Medeski Martin & Wood, whose groove-oriented background makes quite a match for these jazz virtuosos.

The Dirty Dozen Brass Band’s show was packed with more flavor than a fine gumbo and more soul than the M-Shop has seen in awhile. It’s a rare treat when Mardi Gras comes around in such spirited fashion, and for Thursday’s crowd, it was well worth it.
