Form small beginnings on a Victorian farm to globetrotting punk rock icons, the Cosmic Psychos became one of Australia’s most influential bands. Now after thirty years of music making, ‘Cosmic Psychos: Blokes You Can Trust’ documents the highs and lows of the group’s musical career as told by members from the Melvins, L7, Mud Honey, Pearl Jam, and The Hard-Ons with other international music producers and from the Cosmic Psycho band members themselves.

This documentary tells the story of Mudhoney from their very beginnings, to following them on their recent world tour and everything in between. Complete with testimonials from friends, music industry veterans and musicians such as Pearl Jam’s Stone Gossard and Jeff Ament, Sonic Youth’s Kim Gordon and Thurston Moore, Soundgarden’s Kim Thayil and Mudhoney themselves. This is the true story of the founding fathers of Grunge.
