Dec. 27 Ladyfinger w/ Back When, Answer Team & Lightning Bug Slowdown, 729 N. 14th St. 9 p.m., $7, theslowdown.com Ladyfinger has been laying low in 2010, after a personnel change and the launch of singer Chris Machmuller’s pop-soul supergroup The So-So Sailors. But Ladyfinger is back, ready to rip through its fierce take on hardcore-colored classic rock. Ladyfinger still flies under the radar in town, despite 2009’s excellent dusk . Ladyfinger should be in roaring shape as they head a bill featuring some of Omaha’s best wild, indie rock noisemakers. Back When brings an indie prog-metal that focuses on build-and-break drone. Get there early for Lightning Bug, quite possibly the most promising young band in Omaha.
