Having just seen Green Day on their current tour, I'm not the biggest into them but my girlfriend is. I must admit they put on a good show. I've read articles which said Dookie was the spiritual successor to Nirvana (AV Club, for example). I'm curious about your perspectives here. Green Day a real punk band or not? Were they the next evolution of the musical movement started by Nirvana, Soundgarden, Pearl Jam, etc?
