Kid Cudi’s made a lot of famous friends on his yearlong journey from mixtape whiz-kid to 2010 Grammy nominee. He’s guested for the likes of Robin Thicke, Santigold, and Jay-Z, and got help from MGMT, Ratatat, and mentor Kanye West for his 2009 debut Man on the Moon: The End of Day. Cudi’s not wasting any momentum from the success of that Billboard-charting release, and is already back in the studio with—you guessed it—a slew of special friends. Already confirmed for Cudder and the Revolution of Evolution: Snoop Dogg, Pharrell, and Travis Barker. The album credits could get a lot longer if Cudi pulls some names off his collaboration wish list, which includes Green Day, Kings of Leon, and The Killers. Phew! That's a lot of name-dropping. Whoever ultimately makes the Cudder cut, Cudi’s smooth flow over a more rock-oriented album will certainly garner some Grammy nods in 2011.
