mother Earth sound system : keeping techno sexy since 1993.

Mother Earth Sound System is an electronic music event collective, formed of people who love all forms of dance music and the community around sharing the music. Founded in 1993 from the San Francisco bay area rave scene, we have since spread to Oregon, Los Angeles, and are now primarily based in Denver, Colorado. Since 1997, we have been doing free outdoor Full Moon Gatherings throughout the Rocky Mountains, as well as intimate indoor events that focus on eclectic, deep, quality dance music.

Our musical guests have included Robag Wruhme, Donato Dozzy, Surgeon, Joel Mull, Dan Bell, John Tejada, Alexi Delano, Derek Plaslaiko, Matthew Dear, Ryan Elliott, the Kooky Scientist, Greg Schiff, Stewart Walker, Maetrik, Jeff Milligan, Sutekh, Someone Else, Habersham, Jay Haze, Kit Clayton, Richard Devine, Dj Spooky, James T. Cotton, Eric Cloutier, Titonton Duvante, Dustin Zahn and many others.

July 11-13

We are very excited to finally announce the location of the Full Moon Festival 2014, one of our all-time favorite spots: RANCHO DEL RIO! Those of you that joined us there in 2010-11 remember how special and beautiful this location is....

Located approximately 2.5 hrs from Denver, Rancho del Rio offers rafting, kayaking, fishing, hiking, and camping, nestled in a scenic valley with the Colorado River running through it.

Camping will be available from the afternoon of Friday, July 11 through Sunday afternoon. Unfortunately all of Rancho's cabins are already booked; however, those of you interested in cabin lodging should call State Bridge, only a couple miles down the road: 970-653-4444.

Full Moon Festival Passes will be $40. Your pass gets you admission to BOTH Friday & Saturday, with FREE camping & parking. To make event logistics go smoothly, there are no separate day passes. Price at the gate will be $50.

To kick off ticket sales, we are making a limited number of $35 passes available! Once these sell out, the price is $40, but will stay locked at $40 until just before the event.
