It's official: new jack swing is in -- just look at Bruno Mars' recent sweeps at this year's Grammys. And if you need a lesson on the genre, these hip-hop and R&B stars are ready to break down that old-school sound at the New Jack City Jam
. Led by the unique voice and wild charisma of bleached-blond Sisqo (of "Thong Song" fame), Dru Hill ruled the late '90s with massive R&B anthems, including seven Top 40 hits, including "In My Bed," "Never Make a Promise" and "How Deep Is Your Love."Boasting five No. 1 R&B hits, Tony! Toni! Toné! were a true force with successful singles like "Little Walter," "Feels Good," "Whatever You Want" and "The Blues." This multi-platinum supergroup last hit the charts with Alicia Keys, joining her on the hit song "Diary." The star-studded lineup at the Long Beach Performing Arts Center's Terrace Theater also includes performances by Color Me Badd, Al B. Sure!, Christopher Williams, Michel'le, Jon B and Portrait.
