Aloha Mi'Sho — you might know her as Aloha Mischeaux, or, perhaps, just Aloha — has come a long way since her days as an American Idol finalist. Now 24, the singer is shedding her youthful reputation in favor of a grown-up look and sound. So far the maturation is a rousing success: Backed by a full band as an opener for John Legend at this past summer's Fair St. Louis, she wowed the audience with a powerful performance. Other stage appearances find her channeling the best traits of R&B icons: Beyonce's trills and fluid range; Lauryn Hill's depth; Aaliyah's sense of rhythm. Aloha is working on a full-length album, but to tide fans over she just released the Badd EP. The teaser includes the sassy hit "They Be on Me," on which her pitch-perfect vocals mesh well with radio- and club-friendly beats and instrumentation.
