Sleater-Kinney are currently wrapping up the North American portion of their tour behind their terrific reunion album No Cities to Love with a five-night run in venues across New York City. At their gig at Terminal 5, the trio brought out Carrie Brownstein’s Portlandia co-star and self-proclaimed fourth Sleater-Kinney member Fred Armisen for a pretty essential B-52's cover.

Armisen and Corin Tucker share vocal duties for their cover of the 1979 classic “Rock Lobster.” The Saturday Night Live alum gave it his 100 percent, playing a mean cowbell and circling the stage. Needless to say, it looks like they had just about the best time ever; see for yourself in the fan-shot clip above.

Sleater-Kinney have three more shows in New York City before they head to New Zealand and Australia. They’ll play Irving Plaza tonight (Dec. 14), Music Hall of Williamsburg tomorrow and Market Hotel on Wednesday. Get more information at the band’s website.
