The legendary Fred Frith, he of the iconoclastic Henry Cow/ Art Bears/ Slapp Happy axis has since 1974 also had a sideline as a solo guitar manipulator. It’s not enough that he can play anybody under the table in any trad style you can mention. No, Fred brings a massive battery of extended techniques, each more personal and unlikely than the last. Below is a nice little clip which hints at a vocabulary scarcely touched upon by any other guitarists before or since. Long may he mangle.
