It's called <MASS>

It happens once a month in MPLS, and is hosted by the incredible crew at Moth Oddities.

13 5th St. NE
Minneapolis, MN

A different ensemble of sound makers / musicians collaborate each time, trying to hold something together - collaboratively, in real time - for a couple hours.

It's free to attend and is completely volunteer / donation based. Nobody's making $, here, TRUST US…

The "price of admission" is that you:

A) try not to talk
B) shut off your phone and
C) don't screw it up for the people around you.
