In lieu of a box of chocolates, Michael Angelakos recorded an EP of sunny, playfully eclectic electronica tunes for his girlfriend as a belated Valentine’s gift. We can only assume she loved it, because soon Angelakos was passing the same record around to friends and, next thing he knew, Chunk of Change was released by New York’s Frenchkiss Records, and Passion Pit was born. The video for the EP’s “Sleepyhead” was named one of the Top 40 music videos of 2008 by Pitchfork, and anticipation is high for the Cambridge, Mass.’-based Passion Pit’s full-length debut, Manners, due May 18. Live, Angelakos reproduces his one-man keyboard and samples symphonies with a full band comprising Ian Hultquist, Ayad Al Adhamy, Jeff Apruzzese and Nate Donmoyer.
