My Mum was a jazz violinist, as was an Uncle Allie Young...so I grew up with a lot of influences by both, as well as listening to a lot of Django and Grapelli.
Nigel, another exceptional "fiddler" as my Mum used to respectfully call them, was a guy named Joe Venuti...
https://youtu.be/thXi4Ca0sLEHe was the guy (probably not the first) who stretched the bow strings over the top of the fiddle...kinda cool. He shows how he does it on this video...starts at around 5:00 in
https://youtu.be/W3gAypnheyo I love wailing away to a good Gypsy Jazz style on the ole Tyros4...especially doing medleys of the old tunes and using the T4's awesome SA2 Violins and Guitars...happy music indeed.
There don't appear to be any groups in my area playing this type of music.
