Supergrass came out next, really showing up in style. Singer and guitarist Gaz Coombes led the group with deliberate enthusiasm. People compare these guys to a modern Monkees and I was happy to indulge the notion because, like the Monkees, I had fun watching them have fun. I enjoyed the layered vocal harmonies and hooks, but I was really pleased with the clear sound and colorful light show, which aided me immensely in finding my seat between margarita runs. I was so pleased that I hardly yelled at the dude sitting behind me for plopping his foot on my shoulder. SG's banter was limited to a KC BBQ reference and a plug for its newest record, Diamond Hoo Ha. Somehow, I imagine they are usually chattier under less stringent time constraints. For the final two songs, the band dismissed their auxiliary guitarist and the keyboard player. Unfortunately some of the magic left with with them. Things sounded emptier than I wanted and some feedback roared through the PA at just the wrong moments as the band closed up shop. Dash it all.

Finally it was time for The Foo Fighters, a band that doesn't really need an introduction. After all, Foo songs are in rotation on every radio format save R&B and have been practically since the band's debut in 1995.

As a drum and bass buildup chugged, Dave Grohl ignited an awaiting crowd strolling along a walkway that spanned the length of the venue, stopping only for insane bursts of crowd appreciation. They loved him and he knew it and he was about to give them a show worth three times what they paid.

A few news outlets reported that Grohl was experiencing vocal problems after Supergrass' Coombes sang for him during VH1's Rock Honors for The Who a few days back, but he seemed back up to speed as he belted through the band's opener "Let it Die."

It was instantly apparent that this show was going to kick all kinds of rock and roll ass with a heaviness apparently reserved for live shows. Grohl took classic Foo songs and elevated them with an even more dynamic and, when appropriate, aggressive vocal style than on record. Even though I suspect a lot of the screaming was done to cover up his damaged voice on a few sustained singing parts, the double-edged vocal technique ultimately worked.

Another fine addition to the show was the expanded Foo lineup. Foo's usual four-man press photo package started out augmented by a cellist, a third guitarist and a guy on keys. All of the movement missing from earlier acts came blasting in as Grohl and his army headbanged with the flair of Dethklok with Grohl himself acrobating (sometimes you need a fake word to have the best word) around like a young Eddie Van Halen. However, as awesome as the music and lightshow was, the video monitors left something to be desired. Flashing like low-res .jpegs, the images didn't do the rest of the show justice. I mean, if I were an inanimate object working for Grohl, I'd try harder.

After at least a solid hour of greatest hits, the band trekked down the super walkway to a round platform on the other side of the room, which transformed into a light-up secondary stage, complete with two drum kits, an organ and room for three guitarists, a violinist (the cellist from before) and Grohl. "Your seats don't suck shit anymore, do they?" Grohl said to a grateful new side of spectators.

After a few songs Grohl introduced the full band in humorous detail. "We weren't always this super group orchestra," said Grohl, adding, "For each Grammy, we added a member." I have to be a stickler here and point out that they had four extra people on stage while they have only actually won three Grammys. Eh, close enough, especially given the inclusion of on again, off again guitarist Pat Smear. I guess he wasn't technically new....let's just call the joke perfect and move on.

Any way, after introducing the rest of the band Grohl wrapped things up by singling out the band's secondary percussionist, who he insisted was the most important triangle player in rock music. In the guy's defense, he did play a mean triangle solo. "See? All you gotta do is take lessons," said Grohl.

The set on the small stage ended with classic Foo hits, "My Hero" and a transition back onto the main stage with, "Everlong." I have never been so happy to see so many grown men cry tears of joy into overpriced beer - then blissfully drink it.

The rock fest came to a triumphant close as Grohl thanked everyone for coming, recalled the band's first show in Kansas City and soared into the appropriately sentimental "Best of You."

Congratulations Foo Fighters, you've given thousands of concert goers a new theme song to hum if they ever win a big karate match.
