TONIGHT: Dallas native N’Dambi got her start as a background singer for Erykah Badu and now is a well-regarded indie songstress with two Stateside releases under her belt. Joining her on the bill will be D.C. area-based vocalist Tamara Wellons, who had a soulful house hit earlier this year and Howard alumna April Hill, who this past weekend was named co-recipient of the SoulTracks Readers’ Choice Award for New Artist of the Year. Shows at 8 p.m. and 10 p.m. will be held at Bohemian Caverns. $15 in advance.  Tickets can also be purchased at the door.  (DCist/Melton)
