Damn old people.......
97 or 98' Fugazi - in a small club here in Reno, NV
09' Girl Talk - again in a small club here in Reno, not usually my type of music but it was amazing energy and dancing and just a GREAT time
04' Brian Wilson - Front row of his "smile" tour at the Disney Concert Hall in LA. A religious experience.
08' Radiohead - Incredible show in Woodlands, TX
sure there are more but I've been to a lot of shows.
