Tidal and HTC are throwing a massive charity concert in Brooklyn this October, and its lineup is full of the site's most popular and successful artist partners. Head honcho Jay Z, Beyoncé, Prince, Usher, Nicki Minaj, Lil Wayne, and a dozen-plus other artists are set to play Tidal X: 1020 Amplified by HTC (yes, that's the official name) when it hits Brooklyn's Barclays Center on October 20th.

It's the first in a series of Tidal-affiliated "philanthropic music events... aimed at raising awareness, funds, conscious engagement, and dynamic action for transformative and positive social impact worldwide." Tidal is matching all of the proceeds from ticket sales and funnelling the money to selected charities through the New World Foundation, and it'll be soliciting donations from viewers while the concert takes place. Artists will also be collaborating on "specifically chosen songs to promote the message of unity through music," so you might get to see Beyoncé and Prince wailing on a socially conscious ballad together if you're lucky.

Everyone involved is performing for a good cause, but they're also helping to celebrate the glory of Tidal — the service just earned its millionth subscriber. That's a decent number, but it still pales in comparison to Tidal's chief competitors: at least 20 million people are paying to use Spotify's premium version, and Apple Music has racked up tens of millions of trial subscribers with its free period just starting to end. Tidal's earned plenty of notice for its exclusive concert streams and events, including a Jay Z set full of rare songs and a free Prince show streamed from Baltimore.

If you're a Tidal subscriber, tickets to the service's benefit bash go on sale this afternoon at 12:00PM ET. Members of the general public will have to wait until the same time on Friday to make their purchases. If you're not a New York City-area resident — or your buying finger's a little slow — you'll still be able to watch the concert live on both Tidal and HTC's websites, where it'll be streamed for subscribers and non-subscribers alike come October 20th.
