Krist really rocks out on that accordion. JK. It's actually a chill instrumental cover.

According to Rolling Stone, "He played the instrument on Foo Fighters' 2011 track "I Should Have Known" and in 2012, he told Rolling Stone that he had spent much of the previous year learning how to play the Doors' "Light My Fire" on an accordion that Kurt Cobain had given him. He even tried to make the accordion his instrument when he teamed with Dave Grohl and Paul McCartney on their Sound City track "Cut Me Some Slack." But alas, they were not down with that.
