Nihon Kizuna was one of the first charity compilations to hit the virtual record stores in the wake of the March 11 earthquake and tsunami, and went on to raise over $20,000 for the Japanese Red Cross Society. It's since spawned a 34-track bonus album, available on a name-your-price basis (tip: be generous), and now we're getting a belated release party here in Tokyo. Local artists who contributed tracks to the compilation, including Ken-One, Broken Haze, BD1982 and Eccy, will all be doing their thing across two rooms. Expect a fair bit of knob-twiddling and a whole heap of bass. It's free on the door, but they'll be taking donations for the Red Cross instead.
