Without getting too deep into their history, they started out as anarcho-punk squatters in Holland, drifting around the world and influencing or collaborating with tons of seminal underground bands, including Fugazi and Sonic Youth.
Their collaboration with Tom Cora is still my favorite work of theirs, combining punk immediacy with the elegiac “off the grid” sound of bands like Godspeed You! Black Emperor.
