Zero the Hero is the mythological character central to the musical trilogy "Radio Gnome Invisible" by the UK-based-European-enhanced psychedelic progressive rock band Gong.
I am a fan of the trilogy, which contains masterpieces such as Isle of Everywhere. I also quite like some later percussion-oriented albums, as such Time is the Key. For good measure I'm also a fan of some of the work by Steve Reich, especially Music for 18 Musicians.
