the best concert i've ever been to is lilith fair. i went the second year ('98) and the third year ('99) and both were just the best concerts ever. we had artists like sarah mclachlan (lilith fair was, of course, her brainchild), sheryl crow, natalie merchant, the pretenders, sixpence none the richer, mya, indigo girls, jewel, and much much more. it was a whole day thing and they had really cool booths all over the venue. lilith fair was much more than a concert - it was an experience.
it was also my first concert ever and the first time i have ever been in contact with that many lesbians. :lol:
i've also seen john mayer, jason mraz (with chantal kreviazuk), sum 41, alien ant farm (free!), bad religion (free!), and save ferris. i've seen save ferris twice and the first time was also free. i'd say save ferris was my second favorite concert after lilith fair and then john mayer. monique powell is just an amazing performer.
