I'm still waiting for when they're gonna release Who's Next. I mean..that and Nevermind. So fucking awesome.
And yeah, it looks like I'm waiting for that too, TVC. With all the shit people were giving Red Octane for the GH3 controllers (including myself), Rock Band looks to be an even bigger fuck up.
But getting back to Nirvana, both of their live albums are awesome. Nevermind is - as you said - wall to wall awesome as well. I've never gotten into In Utero too much, though.
