After signing as the flagship artist at Jermaine Dupri’s Island Urban Music, rapper Hot Dollar’s first single, Streetz On Lock, was immediately featured inside the DJBooth. Since last May, however, a lot has changed for the upstart artist. For starters, the label has signed a plethora of new artists (Rocko, DJ Felli Fel, 9th Ward), and the follow-up to Streetz, the uber-trendy Side Kick, failed to produce any buzz. With that said, Dollar is back in a big way to start the ’08 campaign and the proof is in the recently featured, Upside Down. To help further publicize his talent level, West Coast DJ’s Rampage and Ill Will have grabbed up Dollar for the new mixtape, Rap or Die Vol. 5; it features the Sean Kingston (and J.R. Rotem-produced) collaboration, On The Block. You hear that? It’s called a turnaround.
