Saying Nirvana's punk is a stupid remark yes they were influeneced by punk but every grunge band was. Bleach had that perfect grunge sound the guitars sounded very similar to bands like Crackerbash and Coffin Break (other grunge bands from Seattle) they had similar hard fast drumming that only grunge bands perfected. Incesticide you can't make any type of come back with that becuase it was a bunch of B-sides. Nevermind had some songs that sounded punk but had that dirty type sound they had back in Bleach just isn't as "hard". In Utero sounds punk but it isn't the record labels and executives wanted that album to be more radio friendly hence why the drums are much more powerful in that album than the rest.
Ohhh and if you think Nirvana's punk please don't dig too deep in grunge music....Becuase you'll get confused hehehe
