With Kanye West‘s Yeezus tour in full effect, concertgoers are getting a sneak peek at some unreleased material. Forty seconds of a song previously identified as “I Am Not Here” kicks in around the 2:45 mark. We only hear Kanye’s voice, the man himself choosing to remain behind the curtain while a group of women stand onstage in blank masks.

The aesthetic of this tour is starting to take shape—simultaneously minimalist and extravagant, Kanye’s sets are monolithic, only to be shattered by the artist’s outfit and presentation. This time around he, too, wears a mask for the start of “I Am A God” after the new track. The merchandise, meanwhile is fascinated with death, black, skeletons, and God. Check out those images below:
