He sounds pretty great here I have to say.
Holy shit does Coma sound good. Really want to hear a solid performance of that one live again. Looks like i'll have a chance here eventually. I thought Wicked Garden and Vasoline were good as well. Interstate was a little funky on some of the artistic choices in the first verse (as mentioned by Blue). I though Jeff's voice seemed to waiver a bit in the chorus here and there... not awful though, and certainly very good for what must have been a nerve-wracking first performance.
The song I missed Scott on the most was definitely Big Empty. No one will ever sing Big Empty as well live as Scott, IMO. I love how he used to hang on the final 'kill'. Definitely msised that from Gutt. On the other hand Still Remains sounded amazing.
All in all, I am impressed with Gutt (I now know its pronounced 'Goot') so far! I hope the new music stacks up, but I feel pretty good that these guys will still give a great live show.
Lets also remember how scott sang those songs with the wildabouts. the end
Made me feel a little bad, but I kind of had to LOL at this.
