Scottish post-rock heroes Mogwai are releasing Atomic, a reworked version of their soundtrack for the BBC nuclear warfare documentary of the same name, in a couple of months. We’ve heard the creeping, dramatic lead single “U-235,” and now they’ve shared another new track, “Ether,” which debuted on Mary Anne Hobbs’ BBC Radio 6 show today. Listen below.

Atomic is out 4/1 on Rock Action. Pre-order it here.
