Now that Saturation III is out, Brockhampton fans have nearly 50 album tracks to listen to from the band this year. But, in case anyone was still looking for more, they quietly uploaded a demo that didn't make the cut to their Tumblr page called "Saturation 389."

The "389" at the end of that title hints at just how productive these guys were this year as they churned out song after song in their Los Angeles home—dubbed the "Brockhampton Factory." Despite the rough opening, this one stands up with the quality of everything else that made the album. You can listen to "Saturation 389" on Tumblr here or stream it below.
