There’s a certain type of act that headlines festivals…BIG ones.
And big doesn’t necessarily mean the most popular.
Festival headliners have some size and scale and tempo and energy to their show. It’s music that has an easier time filling up the space…and since it’s outside in a field, it’s big music for a big space.
It’s easy to think that if you just get popular enough you’ll headline festivals. And there are some genre specific ones that you might…but if you want to be a festival headliner you’ve gotta start putting on a big show with big music just like the festival headliners before you. And you start doing that long before you ever headline.
