Harmonix threw the hottest and most exclusive party of the E3 conference on Wednesday night at L.A.’s Orpheum Theater. The “Rock Band Bash” concert celebrated Harmonix’s upcoming “Rock Band 2″ game and featured a private concert by one of the band’s included in the game’s updated tracklist — The Who. 

When we went to pick up our tickets at the MTV Games E3 showroom late Wednesday afternoon, a line of hopeful concertgoers snaked around the entrance. But their dreams were dashed moments later as their names weren’t on on the exclusive “invite-only” guest list that included “24″ star Kiefer Sutherland and AC/DC drummer Chris Slade.

It was clear we had one of the most coveted tickets in town.

Concertgoers had a chance to try out the new “Rock Band 2″ game before showtime.  About twenty minutes before the concert started, there was a mad sprint to grab the perfect seat. But the Orpheum wasn’t packed by any means, which made it almost like a private concert with the Who. 

Bragging rights aside, the experience was priceless.  Red party cups (yes, the same ones that can be found at any college kegger party) in hand, the audience filled with both young and old Who fans got to enjoy a two hour set. Band members Roger Daltrey and Pete Townshend rocked out to some of their biggest hits, including “My Generation” and “Pinball Wizard,” which the audience granted a standing ovation. 

Townshend, like always, shredded it on the guitar, but also showed off his humorous side. He admitted to disliking the colors of the buttons on the guitar controller (green, red, yellow, blue and orange) and called out the Harmonix employee who designed it. Apparently pink, green and orange would work better, he said. Townshend even poked fun at Aerosmith frontman Steven Tyler and the recent launch of Aerosmith’s “Guitar Hero” edition, referring to it as “that other game.”
