I'm fairly sure that I made a thread like this a year or two ago, but I'm going to do it again.
As a fifteen year old, here's what I had to say about the experience:
What a wild ride it's been...Subject: (orbital) Orbital Live in Toronto
Date: 04 Jul 1997 23:29:17 PDT
Hey!
I just saw Orbital live in Toronto, Canada at Lollapalooza 1997. A lot
of people left just before Orbital, so we ended up in the front row! It
was amazing! That's all I can say... a lot of people didn't get it
though, there was this one guy behind us wearing a Smashing Pumpkins
"Zero" shirt and just sitting there... but I was up dancing, blowing my
whistle, getting other people to dance... Phil & Paul were really nice
after the show, signing all the autographs that people wanted. I got my
ticket & my program signed. And Paul was making a video, and he got a
shot of me! The whole thing rocked, it was totally amazing! That's all
I have to say...

Had I known how much time and money I would spend talking about Orbital, tracking down releases, and travelling all over the place for shows and to hang out with other fans, maybe I would have made a different choice that night. Only kidding! I will never forget the crazy adventures that I've been so lucky to have, thanks to my love of Orbital.
To everyone here:
You guys are the greatest, and I mean that from the bottom of my heart. I've met up with you (and people from the old mailing list and IRC channel) in six different countries now, and it never ceases to amaze me how universally awesome you all are.
Loopz:
You're the man to thank (or blame!) for all of this, really. Crawling through the website for typos and scanning Canadian releases helped me pass many boring afternoons back in high school.

Paul and Phil, if you're out there anywhere, or even if you're not:
Thank you. Your music has been the soundtrack to my life for years now, through moments both good and bad, and I wouldn't have it any other way. I used to sit at night, years ago, writing letters to you that I obviously never sent, talking about how much your music meant to me. I might not be a teenager anymore, and your days as Orbital have come to an end, but all of this still means so much to me.
Here's to many more years to come,
Aimée
