Somasphere is the latest addition to the Maha Music Festival's line-up. The Lincoln-based electronica band presents its dance-flavored sound with the muscle of a live rock band. The band has cemented its regional appeal with appearances in Colorado, Nebraska and at the Wakarusa Festival in Kansas. Maha has yet to announce a final main stage act. There's also the Omaha Entertainment & Arts Awards Summer Showcase, held in Benson July 8 and 9, that will decide the final local stage act. That one will be subject to fan voting during the event's weekend.
