Melvins recruited Crover on drums in 1984 from an Iron Maiden cover band, following original drummer Mike Dillard’s departure. In late 1985, Crover played bass in Fecal Matter, a band he formed with Kurt Cobain and Greg Hokanson. After Hokanson left the band, Cobain and Crover recorded Illiteracy Will Prevail on a 4-track in December 1985 at Cobain’s aunt’s home in Seattle, Washington. Crover played bass and drums on the demo. “Spank Thru” from this demo appears on the Nirvana album Sliver: The Best of the Box. Fecal Matter disbanded in 1986.

Nirvana with Crover played a 14-song show in Tacoma, Washington, on the night of the same day that they did the demo session. Three cuts from the show – Downer, Floyd the Barber and Raunchola/Moby Dick – appear on With the Lights Out. Later in 1988, Crover and Melvins’ bandmate Buzz Osborne relocated to San Francisco, California.

Crover briefly rejoined Nirvana during a short west-coast tour with Sonic Youth in August 1990. In April 1991, Crover drummed on a demo version of Drain You with Cobain on guitar and vocals and Dave Grohl on bass. The track appears on With the Lights Out.

In 1994, Crover founded the band Altamont with Joey Osbourne and Dan Southwick of Acid King. He produced and performed additional vocals on Acid King’s début release that year. During this time he was also married to Acid King’s frontwoman Lori S., but they divorced. Nirvana was inducted into the Rock and Roll Hall of Fame in April, 2014. Although not officially inducted with the band, he was singled out for his work with them during Crover’s successor Dave Grohl’s acceptance speech.
