Had a really good night seeing Underworld play live (even if I was feeling pretty crappy from a cold). The support act were pretty good, Errors, who were from Glasgow. I'm listening to their stuff again now (www.myspace.com/weareerrors).
Underworld blew the place apart. They had a pretty big L shaped set up, with 2 of the biggest Apple Mac screens i've ever seen. They did a 2hour set featuring all the big hits - opening up with Rez/Cowgirl, finishing with Jumbo and playing the likes of King of Snake, Born Slippy nuxx, Push Upstairs and a couple of new ones too. The highlight however was 2 Months Off, when the stage was filled with giant inflatable beams that began to stick out over the audience.
I didn't quite appreciate how old these guys are (i think they turn 50 this year) but they sure put on a great performance, both visually and muscially. Here's the official Underworld review of the gig too:

Nottingham - what a truly amazing vibe! Transforming a day through
your energy & enthusiasm - pumping adrenaline straight into the groove.
You raised the roof & sent us back out on the road tingling & grinning.
Thanks to Errors for another brilliant show.
You go from strength-to-strength.

Also went out to see Evil Nine during the week but they weren't starting till late so I left before they came on.
