To mark the 20th anniversary of Nirvana’s ‘Nevermind’ album, Comedy Central’s Jon Stewart will host a two-hour Q&A session with the surviving members of the band on SiriusXM radio on Sept. 24.

Former Nirvana members Dave Grohl and Krist Novoselic, along with ‘Nevermind’ producer Butch Vig, will sit down with Stewart to discuss the breakthrough album, which sold more than 10 million copies in the United States and spawned the grunge anthem 'Smells Like Teen Spirit.'

SiriusXM also will feature 'Nevermind Radio,' an entire channel devoted to playing the music of Nirvana, from Sept. 23-28 in celebration of the album.

Meanwhile, a Sept. 13 DVD release has been announced for a deluxe edition of ‘1991: The Year Punk Broke,’ the cult classic documentary about indie legends Sonic Youth’s summer ’91 European tour on the festival circuit with Nirvana, Dinosaur Jr., Babes in Toyland and Gumball. The trek took place in August of that year and features rare, behind-the-scenes and performance footage of Nirvana right before ‘Nevermind’ dropped and superstardom beckoned.

The flick was directed by underground filmmaker/video producer Dave Markey, who recounts his experiences trekking across Europe with Nirvana and the others here. “You look at the '1991: The Year Punk Broke,' and Kurt is just smiling through the whole thing," writes Markey. "Those are some of the last smiles you'd see from him before Nirvana became this huge success."
