Have you heard about The Piano Guys?
They play in forest, buildings, on cliffs and trains, even the great wall of china and the salt flats. (It must be hard to get the grand piano up on the cliffs.)
They play using the piano by itself or the piano and the cello or the cello by itself.

I really like their music, my mom also likes their music because they play classical.
