Thank you very much for viewing. This is an official USB drive from the one-night-only performance held in 2010, "Lily Chou-Chou 2010.12.15 Live “Ether”" and a promotional CD containing the audio from Ether. I believe the USB drive contained music videos. "Ether" was never sold on CD, so the promotional CD, which was not for sale, is quite valuable. The USB drive was purchased and has never been used, only opened for the photos. The promotional CD is also in good condition. Thank you. All About Lily Chou-Chou salyu Takeshi Kobayashi
