EL TEN ELEVEN, THE URBAN LOUNGE, Saturday, 9 p.m., $14

It’s tough to come up with a label worthy of the mighty sound conjured by two-piece band El Ten Eleven. Some call their brand on intrumental rock “ambient,” others call it “post-rock,” some simply call it “experimental.” That’s probably the most accurate term, given the array of sounds that the bassist/guitarist Kristian Dunn and drummer Tim Fogarty are able to create live on stage, without any laptops, click tracks or additional musicians necessary. If you’ve never seen them, you’ll be shocked it’s only two dudes on stage. The band’s latest release is an EP called For emily, and the title track is dedicated to a friend who died last year. Other new songs are similarly dedicated to people from the duo’s lives, and the set is a nice addition to an impressive catalog that is now five full-length albums deep. Bronze Whale opens the show.
