The experimental music fan has two very different but equally appealing avant-garde music options this weekend.

On Saturday, hop over to Twins Jazz for a free-jazz concert the likes of which the District doesn't get enough these days, as pianist Joel Futterman and reedist Ike Levin duo it up. Futterman played Twins Jazz a couple years ago with legendary New Orleans saxophonist Kidd Jordan, and immediately won me over with a style that is most easily compared to a somewhat more accessible Cecil Taylor. He's been playing with Levin at least since 2002, and this should be an excellent night for those who miss the shows like this that Transparent Productions used to put on regularly.

On Sunday, a trek up to Orion Sound Studios will be rewarded with a show by the always unpredictable Cheer-Accident, who last played there in April following their performance at Avant Fairfax, pictured above. This long-running Chicago band writes music by throwing genres and expectations into a blender and adding a dash of Zappa-like whimsy—and they come out with something completely different every time they do it. Baltimore bands Armed Elephant and Isthmus open; the latter's Isis/Neurosis brand of metal is great, if an odd fit for the bill.
