Dinosaur Jr. is in the midst of a seven-night run of shows at New York City's Bowery Ballroom, in which the band is performing tons of songs from its extensive catalog and bringing on special guests including Kurt Vile, Fred Armisen and Lee Ronaldo.

Celebrating the 30-year anniversary of the release of the Dinosaur Jr.'s first album, Dinosaur, the band is performing the entirety of the debut album every night alongside a second set of hits and covers, while bringing on special guest every night.

As Stereogum and Brooklyn Vegan report, the first night was jam-packed with fun and unexpected collaborators. Three of the performers shared the stage earlier in the week at the Ground Control Touring 15th Anniversary Show including Steve Gunn, Kim Gordon and Vile.

Gunn came out to sing Dinosaur Jr.'s "Yeah We Know" off of Bug, followed by Eleanor Friedberg joining the stage on "Get Me" from Where Ya Been, closing the performance by tearing up the lyric sheet. Vile performed "Crumble" off Beyond as well as a cover of Neil Young's "Cortez The Killer" later on in the night.

Although, from the posts on social media, it was Kim Gordon's screaming that really stole the show with a performance of "Don't," which Brooklyn Vegan notes is a repeat performance from three years ago when she performed it with the band at Terminal 5. Watch highlights from the Thursday show below.

For Friday's show, they brought out another collaborator from the Ground Control concert, Lee Ronaldo, who sang on another cover of "Cortez The Kill." This time around, Portlandia and The Late Show's Fred Armisen took a seat behind the drum kit for the cover as well as singing and playing guitar on the song "Hey Policeman." Watch the two performances below.
