Linkin Park.
It will be unpopular for many here, but I pretty much grew up through my high school years on LP. My high school years were not the best and LP's music definitely helped me out with some personal issues.
Come my freshman year at UNL. One day, my fraternity vice president says he had LP tickets in Omaha (coming from the 308, I didn't know jackshit getting around Omaha area) and he couldn't go at the last minute due to a midterm. I said I would take them and I called up my really good friend from my high school days who was also attending UNL. We both said fuck it to whatever the next day of classes brought and drove to Omaha.
From there, LP was awesome. The music live was something out of this park. Sometimes it's not the music, but the experience meeting with old feelings was something to never forget.
