Oh sure, Greta been working hard doing her thing, but I nominate this guy
https://www.billboard.com/articles/business/touring/8546726/dennys-punk-rock-show-wacko-bryson-del-valleBryson Del Valle had never promoted a concert before when he signed a paper reserving a restaurant ballroom in Orange County, California.
The 17-year-old from Costa Mesa had been going to punk shows around Southern California for about a year and had an epiphany that if he found a unique-enough venue, he might be able to work with his favorite band, Wacko.
The restaurant "ballroom" is actually the backroom at a Denny's with a fire marshal ordained capacity of 50. It became something epic enough to be worthy of a Billboard article.
