Yeezus takes the turntables for a surprise set at Café Royal Hotel.
According to tweets collated from around the room, Kan-yeezy and his stylist Virgil Abloh played "about 20 new tracks" during a surprise set.
"All hard!" wrote Twitter user @UKJasonPowell, who further described the songs as "dark," hellish" and "groundshaking."
"Was blessed to hear Kanye West's new music played by himself at a private location lastnight," wrote @luxurybsales.
Partygoers also say Frank Ocean was in attendance, but no word yet on how he feels about the new music (his Twitter account was deleted some time ago).
