I have a feeling you would enjoy them still. I haven't seen them this tour, but it's the same lineup as the tour they released all those albums from, and I have the DVD of that tour which shows that they were still great. Matt Cameron is fantastic, and you're still getting the rest of one of the best bands still playing.
I haven't heard the latest record, but I'm sure they still play a lot of old stuff (which is obviously a lot of material to choose from). I think it should be great, and that's why I'm hoping to see them this summer when they come near me.
