Event organizer Chris Kohler, who is also the editor of at Wired.com is not yet able to quantify specifically how successful the event was, but told us that "We're still waiting for final head counts and dollars raised, but it is in the multiple hundreds and multiple thousands respectively." He went on to explain how the organization generated buzz for the event, noting the website, Twitter feed and a Facebook page, but enthused that the most effective method came from a different source. "The most effective way of getting any message out is to have write about it on their website, which they did, multiple times," he said. "Every time Tycho says the word 'Umloud,' our page views skyrocket."

With regard to organizing the event itself, Kohler and his team had a number of challenges to tackle. They needed to keep things running smoothly at an event that raged for eight hours (it started at 6pm and ran until 2am) and they also needed to enforce some rules to ensure things didn't get repetitive. "With over 1,000 songs in Rock Band, we didn't even have to enforce our rule that no song may be played twice on the main stage," he explained. "It enforced itself because of the sheer variety of songs and people at Umloud. We had everything from Boston to Journey to Spinal Tap to Still Alive."

The primary donation generation method for the evening was individuals paying cash to get up on stage and play. The organization offered a number of different "levels" of participation, however. A standard band could pay $40 and wait their turn to play a song, but more dedicated groups could pay $120 to be an "Ultimate Band." These groups got the real rock star treatment with a curtain call time, a custom intro from Chris and his team, plus the ability to reserve a song ensuring no one else would take it. "I was absolutely shocked to see some of the Ultimate Bands," Kohler told us. "I had no idea what they were planning -- one band came dressed as Lego Rock Band, with yellow helmet-masks, and one band came dressed as the characters from Brutal Legend. We did not know they would invest so much effort into it. We are shocked and humbled."

The only problem with the evening was trying to squeeze everything in. "The one little snag we had was the raffle," he explained. "We had so many awesome prizes that everyone who attended would agree that giving them all out was a logistical nightmare. But we did eventually succeed in giving everything away, so there's that. Next year will be much, much more efficient, I promise you!"

GamePro was in attendance (we had a band that appeared late in the evening too, after many drinks) and shot some of the highlights for you.
