Drake, Justin Bieber, Chris Brown + More Perform at Power 106′s Cali Christmas

In the spirit of the season, Drake, Justin Bieber, Chris Brown and more gifted a sold-out audience with knockout performances for Power 106′s holiday concert at the Gibson Amphitheater in Los Angeles on Dec. 16.

The station’s Cali Christmas celebration featured an all-star lineup, including the likes of Wiz Khalifa, J. Cole, Lil Wayne and Big Sean. Naturally, plenty of onstage collaborations took place.

Weezy joined Drake for a live performance of ‘The Motto,’ while Brown helped Big Sean on a rendition of ‘My Last.’ Breezy was sporting his blond ‘do, and hyped up the crowd to a backing track of the hit single, which has helped make Big Sean’s year.

“It’s definitely a breakthrough year for me,” the Detroit native told MTV backstage. “I had my first songs on the radio; I got my first gold and platinum plaques. I’ve been really having a great time.”

Drake dominated the show on Friday night, and as a special treat, the 25-year-old brought the Biebs, his “brother” and fellow Canadian hitmaker, to the stage to assist him on ‘Trust Issues.’ However, the 17-year-old phenom’s newly matured voice seemed to be treading outside of its range.

With its stacked lineup, it’s no wonder how Cali Christmas sold out so quickly. The concert is held annually by Power 106, which broadcasts hip-hop, R&B and dance.
