Yup, that sounds like the usual stuff! The last time I saw them I wasn't amazed either, but then again that was at Wembley which has dire sound and I was half a mile from the stage. It was much more fun when I saw them at Hammersmith (much smaller venue). That time they had a big light display in the middle which was like two UFOs coming down from the ceiling and circling each other. For what felt like 30 minutes... It was good to start with, but went on way too long.
Fingers crossed that this tour is the warm up to go back into the studio. Since they last released an album Mastodon have released 3, Isis released 2 and split up, and I've managed to get a whole degree and two different jobs
It's almost like they compete with Trent Reznor for who can take the longest between album releases.
