Dinosaur Jr. are currently in the middle of a week-long stand at NYC’s Bowery Ballroom to honor the 30th anniversary of their debut album Dinosaur. Every night, they’re performing Dinosaur in its entirety, and they’ve also been playing a bunch of covers and bringing out some special guests. On the first night, they covered Neil Young’s “Cortez The Killer” with Kurt Vile, two nights ago they did it with Fred Armisen and Lee Ranaldo, and last night they did it again with Jeff Tweedy, who also sang on “Tarpit.” On Thursday, they performed “Don’t” with Kim Gordon on vocals, and last night they had Henry Rollins growling all over the song instead. Finally, they also had Charles Bradley lead a cover of Neil Young’s “Heart Of Gold.” (They really like covering Neil Young!) Watch below via Pitchfork.

Jeff Tweedy on “Cortez The Killer”:

Neil forever. #dinosaurjr

Tonight held many epic moments but being within 50 ft of henry rollins was 1) a religious experience and b) better than most sex. #dinosaurjr #happy30th #bowery
