This surprise show, headlined by hip-hop's most popular potheads, sold out quickly, unsurprisingly. This year was Wiz's breakthrough year, scoring hits and Grammy nominations (two for "Black and Yellow," sorry Ravens fans) from his major-label debut, "Rolling Papers." And, well, Snoop is Snoop, a veteran who has transformed from a great rapper to a consistently OK rapper. On record together, they both sound charismatic and at home bragging about their weed habits and the like. The duo's film, "Mac and Devin Go to High School," doesn't have a release date but the soundtrack does — next Tuesday.
