Yes, you read that correctly - people bought tickets for Electric Picnic literally months before they'll even know who's playing at it.
Sure, you might say that they're getting tickets for the experience of Electric Picnic and maybe half the fun of buying it not knowing who you'll get. Not only that, if you don't like who's playing, sure, you can sell on the tickets and you're not losing anything.
While more tickets will likely go on sale in the new year, and the acts are still be announced for some time, it's clearly a testament to how popular the music festival has become.
Or maybe it's a testament to people buying tickets and not knowing what they're getting for it. Who knows.
