Real-world DJs and artists appearing in Grand Theft Auto Online have been a thing ever since the After Hours DLC introduced player-owner nightclubs.
Now, Rockstar is going all out with the concept by opening The Music Locker, an all-new in game club in the Diamond Casino & Resort.
We assume that The Music Locker will open concurrently with the launch of the Cayo Perico Heist DLC, arriving on the 15th of December. There's some construction going on by the Diamond, which will be home to the new venue debuting soon. The Music Locker will be a new social partying space in Los Santos where combat and PvP stays outside.

Rockstar is returning with a new lineup of resident DJs who will provide the music while you dance and drink with your friends and your enemies. The Music Locker will be a top of the line nightclub with the fanciest décor and most advanced sound system money can buy, built right into the ground beneath Los Santos' most prestigious casino.
The grand opening of this new club will be headlined by Moodymann, first resident DJ of The Music Locker. Hailing from Detroit, he brings a mixture of techno and motor city soul to the floor, followed by German troupe Keinemusik and later on Palms Trax, with even more to be announced!
