After Kurt Cobain died Nirvana did a couple of reunion shows with guest singers: Joan Jett, Kim Gordon (Sonic Youth), Annie Erin Clark (The Polyphonic Spree, St. Vincent), Lorde, J. Mascis (Dinosaur Jr.), John McCauley (Deer Tick), Beck and Violet Grohl. We listen to those performances and share some background stories and our own feelings about Nirvana playing without Kurt.
