Rapper Wiz Khalifa and a few of his closest friends -- Schoolboy Q, Chevy Woods and ASAP Rocky -- fired up fans at San Francisco's Bill Graham Civic Auditorium on Friday (4/20) by way of his "4/20 Bake Sale" concert.
Khalifa's is slated to pop up all over the U.S. this summer in support of his solo studio album "Rolling Papers," which peaked at No. 2 on the Billboard 200 after it was released last year. In late July the hip-hop artist will team up with rising star Mac Miller for their "Under the Influence of Music Tour" with Kendrick Lamar, Schoolboy Q and Chevy Woods providing opening support.
SoundSpike photographer Tim Mosenfelder was among the guests with permission to take pictures from the photo pit at the aforementioned "4/20 Bake Sale," and here are some highlights. --View Larger Photos
