In the summer of 2009, they returned to Black Lodge studios to record their first new material in five years, recording twelve tracks intended to be released as three EPs over the course of a year. The band's reunion tour took place in Europe, followed by the US between mid-August and early October. On April 13, 2010 the band released the first EP "Simple Science" on Flyover Records. Despite their reformation, obligations to other projects limited the amount of time the band could spend together. On their 2010 tour, fun. bassist Nate Harold filled in for Rob Pope, who was already committed to touring with Spoon. In 2011 while James Dewees was on a world tour with My Chemical Romance, New Amsterdams regular Dustin Kinsey filled in on keyboards.
