After six years recording and touring with The Material, Colleen started an electropop side project called With Beating Hearts.

"[7] The Material was formed in 2005 in San Diego, with an original line up of Colleen D'Agostino (vocals), Jon Moreaux (guitars), and Noah Vowles (drums).

Before recording their debut EP, Tomorrow, Kevin was replaced by Brian Miller, and Roi Elam joined as a second guitarist.

After recording What We Are, the band performed on the Motel 6 Rock Yourself to Sleep Tour alongside Every Avenue, There For Tomorrow, Sing It Loud and The Secret Handshake and the 2012 Warped Tour.What We Are was released both physically and digitally on January 11, 2011.

The Material returned in 2013 with their second full-length album Everything I Want To Say, released on April 9, 2013, and a west coast tour with Red Jumpsuit Apparatus.

In the fall of 2013, Colleen was asked to submit some top line ideas for deadmau5's upcoming studio album after members of his mau5trap label's staff attended one of The Material's shows.

The EP features productions by deadmau5, Matt Lange and Eekkoo, John Major, Roc Nation producer Ben Harrison and AyB, and Blake Harnage.
