We were treated to another performance session with local singer-songwriter Rob Drabkin last week. On the eve of his annual Birthday Bash concert, Drabkin returned to the CPR Performance Studio to play four acoustic songs - three originals and a cover of Paul Simon's "The Boy in the Bubble."

The Colorado music staple spoke to Keefer about his switch from biochemistry to music, his fascination with musical time signatures, and the influence of Paul Simon on his own music.

Check out our session with Drabkin from 2012, and stream the new performance above!
