Not to stay on the bandwagon or anything, but I'm a fan because Incubus is the only band that has such a great influence on my life. They are the only band that I've actually followed since way back when. Even though I'm not too old, I still think that I've experienced enough to understand and worship Incubus as much as any other fan.

This was my 3rd time seeing Incubus, and I ought to say, it was definitely the best line-up that I've experienced. As others mentioned, it was REALLY surprising to hear Aqueous Transmission..... I soo did not see that one coming, but it was a great way to end the show and leave everyone in peace.
