from Wikipedia:

Action Set is a rock band, stylistically ranging from pop to alternative rock to folk to post-punk. The band often refer to their music as retro-post-modern, slyly citing the inefficieny of any label in describing music in general. The band was formed by Sam Smith (vocals/guitar) and Patrick Hipp (vocals/guitar) in August of 2005 out of need to fill an already booked slot opening for local New York band Red Orange Morning. Smith and Hipp, while coming from similar music backgrounds, had mostly toiled in local bands, struggling to find a group that clicked together as effortlessly as their many influences seemed to. Smith had been performing solo following the dissolution of his band The Arrest (for which an Action Set song was later named) and opened for Red Orange Morning several times, leading to the band asking him to do a solo set at their October 2005 show at WXPN's World Cafe in Philadelphia. With no interest in continuing his solo acoustic career, Smith began looking for another band. He eventually enlisted Hipp to come in as a singer/guitarist, and the two were later joined by former Arrest drummer John Paul Player.

The group quickly gelled and soon were embarking on a mini-tour of the East Coast that would eventually reach as far north as Boston, playing with Miles From Land at PA's Lounge. While in Boston, the band recorded the "Hide & Seek" EP, produced by Miles From Land guitarist Chris Player.

After returning to their home state of New Jersey, Smith and company began preparing for another show at the World Cafe. Shortly before the March 2006 performance, Player left the band and was temporarily replaced with Red Orange Morning drummer Don Ocava. Once the band made it through the show, Ocava stayed on with the band as their permanent drummer. Shortly after, bassist Travis Doyle joined the band, adding a third singer to the band's sound.

Then the four were exposed to cosmic radiation, which gave them each special super powers. Travis was able to perfectly mimic the slang of a 14-year old girl's IM conversation. Pat gained the ability to spit highly corrosive stomach acid capable of disintegrating tempered steel. Sam found himself suddenly able to play world-class polo. And Don, well, we won't tell you what happened to Don. I mean, it was big enough before the accident.
