I like Zakk (esp early Zakk), but this feels phoned in. Maybe it's just me, but when you're covering one of the 'masters', you go note-for-note. I've paraphrased or even just improvised solos from some bands, especially if it's not a "signature" solo that the audience expects. With Lynch or VH or Rhoads or guys from that tier though, I'd play them like the originals, no matter how much time I had to spend in the woodshed. If you're a guitarist of Zakk's level and you're covering Dime's parts in a band that's calling itself Pantera, you play it like Dime. Zakk should be treating it like a tribute band player would. Just my two cents. Doesn't mean I won't go, but I had higher expectations, even such as it is.
It feels like both guitar and drums are missing some of the groove, as I think others have pointed out too. I saw Queensryche on their latest tour, and they were good, but the drums didn't have the right groove either. Just like how Adler's shit sounded off when played by Sorum.
