Psapp (pronounced /?sæp, ?psæp/) is an experimental electronica band. The band, a duo consisting of members Carim Clasmann and Galia Durant, are sometimes credited with inventing a musical style known as toytronica, a form of electronica made with toys and toy instruments (the band uses toy guitars, flutes, and a chicken they named Brunhilda). They have released four albums (Northdown, Tiger, My Friend, The Only Thing I Ever Wanted and The Camel's Back) and five EPs (Do Something Wrong, Rear Moth, Buttons and War, Hi and the iTunes-exclusive Early Cats and Tracks). They composed the song Cosy in the Rocket, the main theme on the hit medical-drama TV series Grey's Anatomy. Some of their other songs have been used in other hit American TV shows such as The OC and Nip/Tuck as well as the UK Channel 4 TV show Sugar Rush.
