A little over a decade ago, Japanese avant-garde metal band Boris released Pink. They haven’t slowed down since, but in a few weeks they’ll reissue their tenth LP and do a few shows where they’ll play it in full. The Pink reissue comes with a 9-track Forbidden Songs collection, which are tracks that were recorded during the Pink sessions but (most of which) have not been released. One of those is “SOFUN,” a delightful thrasher that you can hear via NPR below.

The Pink reissue is out 7/8 via Sargent House.
