Kyle and Michael Trewartha, better known as the electronic music duo Grey, have just released their debut EP Chameleon. The five-track project includes the group's hit single "Crime" f/ Skott, which debuted at #1 on the iTunes Dance/Electronic charts and has been streamed over 2 million times. 

The EP also features "Wings Clipped," an aggressive tune that guest vocals from Avril Lavigne and Circa Survive's Anthony Green.

"Creatively, it was refreshing to let loose, be ourselves, and just go crazy with all the ideas we had bouncing around in our heads once we got in the studio," the group said in a statement. "[O]ur earlier work was more electronic with hints of acoustic layers, but with Chameleon, we flipped that balance and then expanded on it. We incorporated not only more guitar, but also cinematic-like string and horn sections throughout that give the whole EP incredible texture."

Grey's very first tour, supporting Zedd, begins on Friday, Sept. 29. The ECHO Tour will bring Grey to San Francisco, Chicago, Boston, Washington DC and more. You can see all the dates and cop tickets here, and you can listen to Chameleon on Apple Music and iTunes. You can also stream the EP below via Spotify.
