Can't remember all the supporting acts. I've been to many more, but those are some that really stood out. I went to Ozzfest in 97, 99, & 00. 97 was actually pretty good and then I went to Lollapalooza a month later at the same place which, aside from Tool, sucked. Unfortunately, I've missed more than I've seen. In high school, I blew off Soundgarden in 96. I figured they'd be back. I also blew off RATM for the same reason along with being broke.
