Gas Tank Orchestra features a wide range of instruments including strings, reeds, horns, and percussion, all constructed with discarded automobile gas tanks from the streets of New Orleans by Artist/Musician/Scientist Gregory John Wildes. GTO is an orchestra improvising with improvised instruments. ...
The orchestra is self-arranging as it explores the balance (between chaos and epiphany, between conscious and unconscious, between left-brain and right-brain, between this, that, and so on) in staying/changing together.
This not only sounds like interesting instrument-tinkering, but also like an interesting approach to music-making.
Also sounds interesting!
