Apparently Matt Cameron will perform at the SXSW show where they will perform Superunknown in full but after that, that's it. Other than that, no word on the replacement drummer.
I've stated in the SG thread that I cannot wait for this SXSW show. High quality Soundgarden bootlegs are quite rare but these shows usually produce really good ones. Plus it's attached somehow to the iTunes festival...and they are playing all of (arguably) their best album....and they'll probably play some other gems....
Sound good. Keep the recommendations coming. In fact, I should make a list that you can fill in as you go. Remember: They played about 150 different songs at least once on this tour!
