The song that Travis Scott promised to drop during “Astronomical,” his concert on Fortnite Thursday night, turns out to be a collaboration with Kid Cudi — and both the song and the “group” are called “The Scotts.” Slow, menacing and low-key, the song was produced by Daytrip, Dot Da Genius and Plain Pat, with co-production by Scott and Mike Dean — and it’s a long way from Cudi’s rowdy 2018 project with Kanye West, Kids See Ghosts.

Scott’s 15-minute performance Thursday drew the biggest live audience in the hit game’s history, with more than 12.3 million concurrent “Fortnite” players participating, according to Epic Games. The game publisher has set four additional “tour dates” for Scott’s “Astronomical”: Friday, April 24, 10 a.m. ET; and Saturday, April 25, at midnight ET, 11 a.m. ET and 6 p.m. ET. The “Fortnite” publisher said virtual doors open 30 minutes beforehand.

As part of the Epic Games partnership with Travis Scott, “Fortnite” added the artist to its Icon Series to let players get his outfits, emotes, gear and other accessories. Those who attend the “Astronomical” events also are promised access to the Astroworld Cyclone Glider and two loading screens for free.
