Macklemore and Ryan Lewis are set to play a free show for 500 lucky fans at a club in Seattle on Friday night — but those who can’t attend will have another option: The show, which celebrates the release of Macklemore’s new album “Look at the Mess I’ve Made,” will be live streamed by Amazon.

Amazon Music will stream the entire event on the online retailer’s website, starting at 9p.m. PT. However, there’s one caveat: Streams will be available only to users accessing the site with PCs or Macs, according to Amazon.

That means no streaming on phones, and definitely no viewing on Amazon’s Fire TV. An Amazon spokesperson confirmed that the company has the exclusive live streaming rights to the event, so you likely won’t see a live stream anywhere else either.

Still, we won’t complain too loudly: The event is not only free, but also organized to raise money for local social-justice organizations. We’ve asked Amazon who exactly is going to benefit from the event, and will update this post once we know more.
