For someone who likes classical music, I strongly recommend a Blu Ray Disc (concert, audio + video):
http://www.amazon.com/Daniel-Barenboim-Staatskapelle-Berlin-Beethoven/dp/B002P9K9SW/ref=zg_bs_769066_8
It is performed by Daniel Barenboim, one of the world's greatest living classical musicians. In the concert, he played as both a pianist and a conductor. The disc is in HD video (1080p) and HD audio. The disc includes 贝多芬钢琴协奏曲 1-5, total 180+ minutes. If you have a good 5.1 surround sound system, you will feel you are sitting in the concert. Thanks Blu Ray, the new technology that bring us to the new era of the music world. I really enjoy it.
