Ryuichi Sakamoto (坂本 龍一) - Merry Christmas Mr. Lawrence (戦場のﾒﾘｰ・ｸﾘｽﾏｽ) (Piano Cover)

One of the amazing compositions which made Sakamoto international well-known. Very interesting sounding, above all because of the more exotic Asian sound character and the very gentle beginning.
Definitively a tune you should not only listen to on Christmas, lol :)
Played from a transcription.
