Just read the back of the album and you will know something is not right in the land of Gutbucket.

Dive a little deeper and look past the somewhat-freaky picture of a young girl holding a knife and standing next to what looks like a bucket of intestines on the front cover, all against a bright pink background, and you will find an album that is the perfect accompaniment to a bad acid trip.

With off-the-wall song titles such as “Punka– Rumbledink” and “Throsp%,” Gutbucket’s newest album, Sludge Test, a follow-up to 2004’s Dry Humping the American Dream, offers a bizarre mix of Latin, jazz and rock sounds.

Hailing from New York, all members of the seven-year-old quartet have had training in jazz and classical instruments but grew up listening to and playing the rock music of acts such as The Who and Led Zeppelin. Known for its frenetic live shows where the band shows classic cartoons while it plays, Gutbucket has toured all over the United States and Europe.

Drawing on more modern influences such as Mr. Bungle and Lightning Bolt, Gutbucket takes the wonderful world of improvisational jazz, gives it a shot in the arm and pushes it in a new direction on Sludge Test.

Horns, saxophones, guitars and drums work themselves into a frenzy before coming together to form a whirling dervish of sound. Conventional song structure is thrown out the window and replaced by sometimes seemingly random ramblings on guitar and saxophone.

To be fair, some of the tracks such as “Circadian Mindf—” and the aforementioned “Punka– Rumbledink,” do build slowly and end with a big bang. Others, such as the opener “Money Management for a Better Life,” start quick and keep the chaos going constantly. “Plague of the Legions” sounds like something heard at a salsa club and is a good tune to get the hips moving.

Like any true jazz band, Gutbucket keeps vocals to a minimum on Sludge Test. Besides guitarist Ty Citerman ranting in the background on “Underbidder,” there is no singing to be had. There will be no sing-a-longs in the land of Gutbucket, only dancing and humming.

Occasionally sounding like a blend of Phish, the Flaming Lips and the new Mars Volta — but without vocals and not as good — Gutbucket’s Sludge Test is a weird mix between improvisational jazz and a jam band.

Gutbucket kicks off its international tour on March 12 in Chapel Hill at The Cave.
