Wikipedia : This day (September 29, 1942), in Avranches, France, is born Jean-Luc Ponty, a French violinist and jazz composer.
Jean-Luc Ponty : He is widely regarded as an innovator who has applied his unique visionary spin that has expanded the vocabulary of modern music. At first, the violin proved to be a handicap; few at the time viewed the instrument as having a legitimate place in the modern jazz vocabulary.
@ allmusic : It has been a long, fascinating odyssey for Jean-Luc Ponty, who started out as a straight jazz violinist only to become a pioneer of the electric violin in jazz-rock in the ’70s and an inspired manipulator of sequencers and synthesizers in the ’80s.
@ last.fm : He sometimes also uses a 6-string electric violin called the Violectra, with low C and F strings – not to be confused with the violectra he played from the late 1960s to the mid-80s which had 4 strings, but tuned an octave lower.
