In a just world, UK rockers Foals would be as big as contemporaries like Alt-J and Mumford and Sons, headlining an arena tour through the states. As it stands, the Oxford act has become one of Britain's most prominent alt-rock acts, with a major label record deal and the clout to release its sprawling new album in two parts. For the most part, Everything Not Saved Will Be Lost Part 1 sticks to what the band does best, melding tricky rhythms with driving synths and proggy guitar riffs across a series of larger-than-life anthems. While the execution doesn't always live up to Foals ambitions (or justify its scale), seeing the band work out the material's kinks onstage should make for an invigorating evening. Make sure to get to the Riviera Theatre early to catch sets from Atlanta power-trio Omni and post-punk act Preoccupations.
