Hometown hip-hop stars Macklemore & Ryan Lewis are performing a free concert Friday night in Seattle and Amazon will stream the event live to fans around the world.

In a partnership with Amazon Prime Music, the musicians are performing in support of their new album, “This Unruly Mess I’ve Made.” The first 500 people in line at Neumos on Capitol Hill will gain entry for the 9 p.m. show. The event will benefit local social justice organizations.

Amazon says the concert will only be viewable on desktop Macs or PCs, not mobile phones or tablets. As for browsers, Chrome, Opera, Microsoft Edge, Internet Explorer 11 (on Windows 8.1+), Safari, and Firefox (version 42+) will be supported, Amazon says.

If you can’t stay up late in other time zones, you’re out of luck because the concert will not be available for playback after the live stream.

This isn’t the first time Macklemore & Ryan Lewis have teamed up with Amazon. The stars who found great success with their 2012 album “The Heist” played for Amazon employees in a concert at CenturyLink Field last summer.

The new album from the duo will be out Friday. In a video post on their website, Macklemore talks about the process that went into making “Unruly Mess,” which involved disappearing into the woods and figuring out how to use his voice again.

Amazon previously ventured into live streaming by offering President Obama’s final State of the Union address.
