What is MagmaFest?

MagmaFest is an annual music festival organized by Hollow Earth Radio, a community FM and online radio station and arts hub located in Seattle. We are celebrating our 20th anniversary in 2027!

History & Mission

The first Magma Festival was in 2008. We wanted to create a public forum for the people of Seattle to experience underrepresented sounds and perspectives. We strive to select bands and performers that are really, really underground or making weird sonic stuff that we feel should be given more exposure.
During our booking process, we also keep diverse lineups in mind. We look for people who are from underrepresented communities—people of color, people of all ages, women, queer-identifying people, people with disabilities—are given a place in the lineup.

 “Hollow Earth Radio seeks to examine the unknown and the periphery of music and culture, to discover what’s going on right beneath our feet. MagmaFest is the physical manifestation of it.”

How can a person get involved with Hollow Earth or Magma Festival?

It’s SUPER EASY TO BE A PART OF IT. We want people to make the radio station better, especially if they’ve got a show that fits our mission of “underrepresented sounds and perspectives.”

COME MAKE IT HAPPEN. Take over the space!
