The Avalanches’ landmark debut Since I Left You turned 20 last November. Tonight, they’re releasing a new 20th anniversary edition of the album featuring featuring unreleased remixes from artists like Black Dice, Leon Vynehall, Sinkane, and Carl Craig. But before that comes out, they’re sharing a new version of “Tonight May Have To Last Me All My Life” with a previously unheard vocal contribution from the late, great underground rap legend MF DOOM, who passed away last October. Listen to that below.
