After over half a million votes were cast online, the 16 acts vying for the cover of Rolling Stone – as well as an Atlantic Records contract – have been narrowed down to two finalists: Canadian boogie rockers the Sheepdogs and Los Angeles singer-songwriter Lelia Broussard!

Voting in the final round of the competition is open now through July 1st. If you're not already familiar with the bands, you can check out videos, free downloads and interviews, or catch them when they play an epic battle of the bands at the Bonnaroo festival on Saturday, June 11th from 2-3 p.m. Festival-goers will be able to text in their votes during the performance.

The winner of the contest will be announced on the August 1st episode of Late Night with Jimmy Fallon – and they'll go on to make their live television debut on the show. From there, they will appear on the cover of the August 18th issue of Rolling Stone and begin work on their first album for Atlantic Records.

We recorded Lelia Broussard and the Sheepdogs' reactions to the big news. You can watch a video featuring highlights from their responses below.
