Waltz from Big Shake by Thomas Diethelm
the Swiss spear champion and nylon guitar virtuoso made success in Europe mid 80ies using a unique kind of LiveLooping on a AMS DMX 15-80S digital delay and pitch shifter and a Paradis Hexaphonic guitar with Polydistortion.
some years he just sold dried spiced fish.
2005 Guiteros was some solo comback.
then he lost his place and had to sell his instruments and died in 2013 rather miserable.
