Bo Burnham doesn’t play many of the old songs anymore, the ones that made the Hamilton native a YouTube phenom before he even finished high school. That was just five years ago, but the 22-year-old has already moved on. He took a couple of years to concentrate on writing, staying in the public eye by touring, but not releasing a new album or special.
Now he returns with a new scripted sitcom called “Zach Stone Is Gonna Be Famous” (which airs Thursday nights on MTV), and a well-honed hour of live comedy he hopes to film for release at the end of the year. The kid who once recorded awkward white-boy hip-hop in his bedroom is growing as an artist. His new material includes “Nerds,” an ode to his younger fans who might feel uncool, and some experimenting with sketch comedy. He’ll donate his proceeds from Thursday’s show at the Berklee Performance Center to One Fund Boston. We spoke to him by phone from Boulder, Colo., at the beginning of his new tour.
