The "Frisch Gestrichen" mini album got released by the Spring String Quartet in 1998. It presents three excellent performances: Stevie Wonder's 'Sir Duke', Frank Zappa's 'Peaches En Regalia' and Jimi Hendrix' 'Gypsy Eyes'. Beautiful.
I had never heard of it until a couple of weeks ago.
A fine addition to The Others Of Invention.
