Long-dormant Canadian post-rockers Godspeed You! Black Emperor are set to return to the stage this December with a headlining set at All Tomorrow’s Parties’ Nightmare Before Christmas, but as anticipated as that appearance is, the band—which is also curating—may have just one-upped itself by adding “Weird Al” Yankovic to the lineup. According to the festival website, Yankovic’s appearance will be his first-ever European show—and if said website can be believed, he’s going to make the most of it with a set featuring “a full band, huge video screens, numerous costume changes and much more.”
