I've just recently started to follow the group Passion Pit. They formed out of Cambridge, Massachusetts in 2007. Mostly falling into the 'Alternative' category of music they play a variety of electronic/pop music. The group started off as a solo act by Angelakos, but after a performance he was approached by Ian Hultquist to put together a group with his current material.
Their first debut album was released in September of 2008 under the name of 'Chunk of Change'. It's release was slow at first but started to gain steam as a few commercials started using 'Sleepyhead' in them. The second album they released was 'Manners' in may of 2009. This album saw far more success than their first and is still growing.
Anyhow, here's a sample. Hope you enjoy it!
