Can we get a quick round of applause for bands that are doing something not just different, but way different?

No really, I’ll wait. Put down the coffee. Park that cereal spoon. Put your hands together — softly, if need be — for Human Ottoman, a Eugene-based trio that summarizes its unusual sound as “polyrhythmic world metal.”

Human Ottoman is Matthew Cartmill on cello, Susan Lucia on drums and Grayson Fiske on vibraphone, which is kind of like a xylophone or glockenspiel but it’s equipped with a pedal that allows the player to sustain notes.

Together, these three make a restless and wide-ranging noise. Sometimes, they sound like a band that blends classical music, jazz and global (particularly Middle Eastern) flavor. Other times, they sound like that same band playing its instruments with power tools in the back of a delivery truck taking right-angled turns at 45 mph. Their Facebook profile lists influences from The Bad Plus and Mr. Bungle to Charles Mingus and Tool, which sounds about right.

It’s adventurous stuff, and adventure is good. On its new album, “Power Baby,” Human Ottoman shifts from conventionally tuneful to chaotically heavy and back again, over and over. You can hear all of that and everything in between at www.humanottoman.com.

Human Ottoman ; 7 p.m. Wednesday; free; McMenamins Old St. Francis School, 700 NW Bond St., Bend; www.mcmenamins.com.
