Let me clear my throat:
. . . And the Goldenvoice/Radio Free Concert series in Hawaii from 1992-1998. I was a DJ there and got to see some great concerts all for free . . . NOFX/Offspring/NoDoubt/311/Pennywise/Sublime/Suicide Machines/Fudazi/Suicidal Tendencies/Reel Big Fish/Def Tones/Filter/Yellowman/Weezer/Outkast/The Roots/Cypress Hill/Janes'Addiction . . .
Also, the Coachella music festival last year.
EDIT: How could I forget Ted Nugent, Johnny Winter, Springsteen, Queensryche, Judas Priest, Tom Petty, Rush, Megadeth, Queen, Echo and the Bunnymen and Metallica concerts?
