I've not been to many festivals even in the United States - I had an opportunity to go to Bonaroo back in the first couple of years, but didn't do it for whatever reason. There haven't been a whole lot of other opportunities since then - most of the US festivals are on the coasts or elsewhere. Lollapalooza has really not been that interesting to me, and that, along with the much smaller (snooze) Pitchfork festival are probably my closest options.
I discovered this high-def only channel when we bought our new TV called Palladia, which seems to be an outlet for Viacom to repurpose HD content, but good HD content. It's actually about the (mostly live) music, as opposed to their mainstays which have very little to do with music anymore and are more lifestyle oriented (and surprisingly, we don't get in HD yet, but we do get this other, awesome channel)
Watching Palladia has helped fuel my wish to someday go to the Glastonbury music festival to fuel my love of multiple different kids of music (specifically rock and dance), and while I'm at it, take in some other things that go on at that time of year. It would involve going over to the UK and Ireland for 2 to 3 weeks to take in Glastonbury in the UK in the last weekend of June and the Oxegen festival in Ireland which is usually the second weekend of July. In between, I'd want to take in some tennis at Wimbledon (my favorite Tennis tournament for whatever reason) and the sights of Ireland and the UK. I haven't spent any time anywhere other than London and I was 15 when I was last there, so it'd be totally different.
I feel like I'm skewing on the older end of the audience for these festivals given the crowds I've seen in various films of the past festivals. And I could potentially skip the Oxegen festival if the lineup was close enough (the same bands tend to do the festival circuit in Europe, which lasts all summer). Going to Glastonbury would probably be enough.
I have no idea how hard or easy it is to get tickets to any of these things either - Glastonbury sells out in less than 24 hours and many people get shut out. I have no idea if there's a secondary market for it. Wimbledon also seems like it'd be an expensive endeavor. I'd also have to figure out how to work the family into the mix, a tougher proposition when you have a wife that's not a huge live music fan and small children, not compatible with anything.
It's still just a crazy idea in my head, but maybe it'll happen someday.
