ah moonlight sonata:thumbsup:... slip, you dont have to be a fan of classical to like this song, it's just a beautiful song on the piano.

check out Mogwai - "Auto Rock" or "Freind of the Night" ( post-rock not classical but includes some very good piano)

or if it's the progression you like, check out Godspeed You Black Emporer - "Rockets Fall on Rocket Falls" (amazing song in simmilar key and progression done on guitars and strings)
