This song by Clemens Ruh is one of the most beautiful piano works I have heard in 2015. But this guy is not "only" able to compose some nice Ambient works. He knows how to put together some proper tracks for the dance floor.
His remix of Chymera's "Fathoms" is only one of many great examples. However, "Preen Your Own Wings" is pure chill and makes you feel comforatable, whenever you listen to the track.
