Billboard, Sonicbids

Billboard readers will vote on five finalists to decide which act wins a trip to Las Vegas and the chance to open the Billboard Music Awards after-party.

After a night including performances from Prince, Taylor Swift and Lil Wayne, Billboard is looking for one act to take the Billboard Music Awards from the party to the after-party.

One group will get to follow the evening of superstar acts with an official gig at the Billboard Music Awards after-party in Las Vegas on May 19. Bands who think they're ready to follow up the Purple One can submit their music via SonicBids, with Billboard readers to vote on five finalists to take the final slot starting May 8.  The winning act will be flown to Vegas to open for the to-be-announced after-party headliner at the Marquee at the Cosmopolitan.

The Billboard Music Awards, which will include performances from Prince, Swift, Wayne and acts ranging from Nicki Minaj and Justin Bieber to the Band Perry and Kacey Musgraves, will air live on ABC at 8 p.m. ET from the MGM Grand Garden Arena. "30 Rock" alum Tracy Morgan will host, with Don Mischer producing.

As previously reported, Sonicbids, an online service that connects musicians with booking, promotion and marketing opportunities, has joined Billboard and Backstage in the recently formed Billboard Group, a division of Guggenheim Digital Media.
