Nirvana have always been slightly over rated in my opinion, I prefer their acoustic red neck music really. Frank Black/PIxies were a great influence on Niravana, and they were/are way better. I'm still to this day annoyed with myself for not going to see them when they played my student union in 1991 though.

I prefer Pearl Jam personally between the two though. I had to opportunity to see them for free recently, I get occasionaly jobs like this, I got paid at the end for loading the equipment onto the trucks after the gig. But they made us wait outside the arena for the last hour of the gig and we missed all the great songs like I am alive, and the cover of Neil Youngs Rockin in the Free World! We got right up the front in the VIP area for the first half though, and it was an amazing gig.
