Yesterday, a rare event occurred. Jay Z tweeted, albeit it was just about promoting his subscription streaming service, TIDAL. Hov announced that TIDAL had reached the 1 million mark in users, and there would be an event on 10/20 in Brooklyn to celebrate.

Today we have the details on that event, which is actually a massive concert that's going down at Barclays. The "TIDAL X: 1020" concert will feature performances from Jay Z, Beyonce, Nicki Minaj, Lil Wayne, T.I., Fabolous, Damien Marley, Usher, Prince and more. It also isn't limited to TIDAL users, although if you are member you'll get first dibs at purchasing tickets.

Tickets will range from $74 to $244, and they'll go on sale for TIDAL subscribers September 30th at 12 PM EST. The rest of us regular folk can purchase tickets on October 2nd at 12 PM EST.

All proceeds from the event will go towards New World Foundation, with the goal to "benefit nonprofit organizations dedicated to advancing positive community relations and effecting systemic change for the development and sustainability of just societies, this inaugural event's philanthropic focus."

If you can't make it to the show, you'll be able to live stream it via TIDAL-- and once again they've opened it up so non-members are also able to stream, free of charge.
