Beyond Wonderland at San Manuel Amphitheater While most of the EDM establishment is cavorting at Winter Music Conference in Miami, some of the genre's biggest names will head to L.A. for Beyond Wonderland, one of Insomniac's bigger annual events. Swedish House Mafia's Steve Angello, Afrojack, pop titan David Guetta and rising acts such as Maya Jane Coles, Art Department, Damian Lazarus, Arty and Rebecca & Fiona top a pretty thorough bill of contemporary EDM. San Manuel Amphitheater, 2575 Glen Helen Parkway, San Bernardino. 4 p.m. Sat. $75-$150. Insomniac.com
