Sensurround + B-Sides is a 2008 CD/DVD release by Japanese musician Cornelius (Keigo Oyamada) that serves as a companion piece to his 2006/2007 album Sensuous.  Now discontinued in the US. These are the last NTSC copies.  Comes with a CD of the B-sides.

These are the tracks available on the Gum ep. Featuring contributions from legends like Ryuichi Sakamoto, Prefuse 73, Petra Haden, and The Books, this EP is a rare gem for fans and audiophiles alike.
