I have contributed a special unreleased track to http://kizunaworld.org/english/index.html (founded by Ryuichi Sakamoto 坂本龍一 ).  All donations, in full (minus the paypal transaction fee), will go straight to victims to help rebuild and maintain the areas of Japan affected by the tsunami.  This is done without a label or complex organization.  There also a multitude of other special tracks by other respected musicians available for a donation to tsunami victims.
