The music business is in the plot
A promoter, a studio owner, an act and the money behind them, all introduced in the same official material and all connected to each other.
Every Grand Theft Auto has had music in it. This is the first one that has the music business in it.
Four of the characters Rockstar has introduced work in or around that business, and they are connected to each other rather than scattered across the map. That is a structure, not a coincidence of casting.
| Character | What they do | How they connect |
|---|---|---|
| Dre'Quan Priest | Promoter, moving into management | Works with Boobie Ike, manages Real Dimez |
| Boobie Ike | Owns the recording studio | Backs Dre'Quan, connected to Raymond |
| Real Dimez | The act, a rap duo | Managed by Dre'Quan, recording at Boobie's |
| Raymond | Money and reach | Connected to Boobie Ike |
Why this is new
In previous games the music industry was a joke told on the radio. Love Fist were a parody hair metal band you ran errands for in 1986. Madd Dogg was a rapper whose career you rescued in one strand of San Andreas. Both were self-contained, and neither connected to anything else in the world.
Here it is a network: a promoter, a studio owner, an act and the money behind them, all introduced in the same official material and all pointing at each other. That is how Rockstar builds a thread it intends to run through the story, in the same way the Grand Theft Auto V heists were all built around one fixer.
What it probably means mechanically
Nothing here has been confirmed, and this section is inference rather than reporting.
A studio you can visit, an act whose career goes somewhere, and a promoter who books shows are the raw material for the kind of business layer Grand Theft Auto V put behind Franklin and Trevor. Rockstar has also shown nightlife venues and a cabaret at Port Gellhorn, which are the sort of places a booked act would play.
None of that has been demonstrated. What has been demonstrated is that the four people above exist, have jobs in music, and know each other.
What is not known
Whether the studio is enterable, whether Real Dimez appear on the radio inside the game, whether any of this is playable rather than narrative, and who voices any of it. Rockstar has named no voice cast.
