Isaac began his career answering phones at a mid-tier booking agency. Using his unemployment benefits and a modest severance from his boss he cooked up the idea of starting the independent label StarTime International. From 2000-2006 he released albums by the French Kicks, Brendan Benson, dios, The Joggers and the Walkmen. To the chagrin of everyone involved, particularly the bands, the label was only modestly successful.
In 2006 Steve Barnett of Columbia Records introduced Isaac to Arcade Fire and Bjork manager Scott Rodger of Quest Management. He joined the company and helped run the Sony funded venture Almost Gold Recordings. Together they signed Peter Bjorn and John, Does It Offend You Yeah, and released Calvin Harris’ debut album in the US.
In 2008 he restarted StarTime as an imprint of Columbia and joined its AnR staff. He’s been there 10 years and signed, among others, Passion Pit, Madeon, Foster the People, Lewis del Mar, Wet, and Coin.
