Alongside December's Doomsday Heist, GTA Online introduced Blonded Los Santos 97.8 FM—a Frank Ocean-hosted radio station, that marked the game's first new music in over two years. Now, it appears Rockstar is lining up some new beats by way of techno DJs Tale of Us, The Black Madonna, Solomun and Dixon. 

As reported by Resident Advisor, The Black Madonna's official Twitter posted the following collaboration flyer which lists the above acts, Los Santos and "Summer 2018."
