YC's Big PlayHip-hop fans no doubt remember Young Chris, a member of former Roc-a-Fella act Young Gunz. But there's another Yung Chris rapidly making a name for himself these days.

Under the moniker YC, the Decatur, Ga., native is climbing the charts with "Racks," featuring Future. The debut single jumps into the top 10 on Billboard's Mainstream R&B/Hip-Hop chart and moves 14-12 on Hot R&B/Hip-Hop Songs.

The Big Play/Universal Republic newcomer explains that the song came about when the subject of racks arose while having some fun recording one night. The term "rack," for the uninitiated, refers to a stack of money equaling $1,000. As to why the song is catching on so fast, YC says, "It started in the streets. Clubs started playing it, then radio picked it up [including Atlanta urban outlets WHTA and WVEE]. And it's worked its way up from there."

Before attracting the attention of Universal Republic executives, YC initially signed with Big Play Entertainment after being noticed last summer by the company's president, KV. "Along with the music he was making," KV recalls, "we liked Chris' personality, his swag and overall understanding of the music industry."

Currently on a national club tour that extends into June, YC is also recording his still-untitled debut album. Among the collaborators he's been working with thus far are producers Cool & Dre and Drumma Boy. Coming soon is the "Racks" video filmed in YC's hometown, featuring cameos by Gucci Mane, Shawty Lo and Yung Joc.
