Might be an outlier here but I have gone to maybe 3 concerts in my life for fun/without a camera. Usually, if I am at a concert it is because I'm shooting for the artist.
To answer your question: I haven't been to a festival yet but I would love to shoot at Coachella or EDC next year. The reason those are on my list is that they are the biggest and draw a ton of cool artists I would like to meet. If I were to go to a festival for fun I guess it would be Governors Ball just because it's so close.
Also side note, once Kanye drops his album and announces his tour, that will be the first artist to get me to buy tickets. I might even go as far to travel to a far-off venue to see him.
I actually don't have a favorite music festival! As someone who's been a part of the planning for such an event, I've seen the hard work that needs to happen for a festival to be successful. It's very easy for something to go wrong and the things that go right are often unappreciated. While I wouldn't trade those experiences for anything, they've also left me somewhat jaded towards the entire festival atmosphere.
My favorite music festival is Coachella— however, purely from a media consumption standpoint. I've actually never attended a music festival before. But Coachella is my favorite one to read about afterwards, particularly about the cool brand activations that took place (loved the Hotel Revolve and Amex Platinum House). It is also the best for stalking all my favorite celebs and influencers Instagram posts.
There is no particular reason I've never attended a music festival before. It's just never been something that I am that interested in investing my time and money into. I'd much prefer a small, local concert by one of my favorite artists than a festival. However, if I DID attend one, Stagecoach would be my first pick. LOVE country music!
I haven't been to many music festivals but last year I attended Panorama, which was a great experience. I mostly went because Solange and Frank Ocean were headlining but overall I think the environment was really unique and not oversaturated with branded activations. Also, I'm from the Midwest and Lollapalooza is one of the bigger events in this region. It's a great way to see artists from all tiers in one place that happens to be close (at least for me) and it's a Chicago staple.
