Drake, hip-hop's current reigning angsty king, headlines Power 106 FM's Cali Christmas, a compendium of rap-adjacent artists including Big Sean, J. Cole and YG. Drizzy Drake is clearly the main draw here, as the smash success of his new album "Take Care" indicates, and its woozy, piano-driven atmosphere will be an interesting fit in a large amphitheater. Gibson Amphitheatre, 100 Universal City Plaza, Universal City. 7:30 p.m. Fri. $45-$125. livenation.com.
