And now for something completely different!
The guitar featured in this performance was made by Greek luthier Yorgos Kertsopoulos. He describes the instrument as “designed and constructed by me in 1996 and it is a multi-timbre rectangular guitar with movable back pedal. As the guitarist plays, by pressing slightly the guitar’s back to her/his chest, pedal effects on the sound are produced”

Here is John Feeley playing the same piece on a conventional classical guitar.
