I hear ya. I remember Lollapalooza at the Gorge at George, Wa. in 1996 featuring Metallica (the unannounced special guest turned out to be Soundgarden, which turned out to be their last concert before their break up), there were many groups on 3 stages. I really liked a then no name group called Sponge.I attended every Ozzfest from 2001-2007. The list is huge from those events alone.
