Seattle grunge met North Carolina bluegrass as Chris Cornell sat in with The Avett Brothers for last night’s performance on Late Night with Jimmy Fallon. Together they debuted the song “Vanity”, off Avett’s forthcoming LP, Magpie and the Dandelion, due out October 15th.
However, that wasn’t the only unexpected moment on last night’s show. The Avett Brothers also showed off their funny side in a spoof infomercial advertising The Avett Brothers Sing Heavy Metal. At last, you can hear their takes on Iron Maiden’s “Run to the Hills” and Black Sabbath’s “Iron Man”.
