If I had to make picks for artists or groups that are new, and wish people would get exposure to:
Big Grams - 1/2 Phantogram and 1/2 Big Boi (Who's 1/2 of Outkast). Two very talented and respected artists who've killed it. And they come together to make an awesome mash-up/collaboration.
Rdgldgrn - Nothing ground-breaking technically speaking, but they meld hip-hop, rock and pop flawlessly. Catchy and fun. And you have to respect a band taking a shot mixing genres while alienating the genre's respective fans.
