So whats next for Caleb?
"I got a double mixtape I'm gonna try to release before South by Southwest," says the young rapper. "Half of it will be an experimental album, and the other half will be more urban pop."
The pop element's an important one -- it's fairly integral to his sound, a la B.o.B. and others who are continuing to blur the lines between hip-hop and pop.
"I'll probably be singing more on this mixtape," Mak says. "Kind of like Drake or Kanye's 808s and Heartbreak."
