There was a local radio station near me that would host a summer festival every year. The tagline was ten bands for ten bucks.
And we’re talking big name bands too - Smash Mouth, Bush, The Offspring. Usually 6-7 big bands and a couple just starting to break into the scene who were always huge 1-2 years later.
They just rebooted it this year. $50 plus fees for 6 bands. It’s still a decent deal considering but not the same as it used to be.
