Jay Z is re-launching TIDAL, the high-definition music service he recently acquired, tonight at 5 pm ET. To celebrate the occasion, he’s just released a promo that features the rapper having an epic board meeting.

In the clip, music artists who have aligned themselves with Hov’s new streaming service (by changing their Twitter and Facebook profile photos to cyan blue) all gather either in person or via video to witness history in the making.

The star-studded cast includes Beyonce, Rihanna, Madonna, Nicki Minaj, Kanye West, Usher, Alicia Keys and others — but will it be enough to make this brand a success?

Streaming services is a crowded market, with Spotify dominating the playing field and Apple recently teaming up with Beats Music.

Check out the A-list teaser below.
