Listen to Lollapalooza Radio on iHeartRadio

(São Paulo, Brazil)  -  Queens of the Stone Age not only brought an end to a year-and-a-half-long hiatus from the stage this weekend, they also showed off some new material.  On Saturday, Josh Homme and company played Lollapalooza Brazil and debuted the new track "My God is the Sun." Jon Theodore from the Mars Volta is now drumming for the band.

The song is fans' first real taste of "...Like Clockwork," which is expected to be released in June.  The band offered snippets of a few tunes via their website after they officially announced the album's release last month.

Meanwhile, a host of other rockers took the stage in São Paulo along with Queens of the Stone Age.  The Killers, the Flaming Lips, and more helped get things started on Friday, while the Black Keys, A Perfect Circle, and Franz Ferdinand were just a few of the acts who kept things going on Saturday.  Pearl Jam wrapped up the second edition of Lollapalooza Brazil on Sunday.
