Cinco de X with Flogging Molly, Hollywood Undead

Our friends at X96 know how to throw a party, although I’m sure when they booked this two-stage rager, they were expecting spring to have actually sprung by now. We’ll just have to leave it to the bands filling two stages at the Great Saltair to keep the crowd warm. The indoor stage is headlined by Flogging Molly, the Celtic-flavored poppy punks who are prepping for the release of a new album, Speed of Darkness, at the end of May. That band is always a treat live, and their last album, 2008’s Float, debuted at No. 4 on Billboard’s album-sales chart. Hollywood Undead headlines the outdoor stage, and the masked rap-rockers are currently wallowing in the success of their second album, American Tragedy, probably by feeding on the brains of adolescent children with poor taste in music. 10 Years, Drive A and Middle Class Rut are among the other bands playing the festival. Great Saltair, 12408 West Salt Air Drive, Magna, 6 p.m., $31 advance/$38 day of show
