EphShap has discovered "Chassidic jazz."
This is nothing new. Jazz exploration of Jewish music has been going on for a long time.
There is also "Carlebach jazz," (click on the recordings page for a swinging jazz guitar version of Mizmor L'david), "Klezmer jazz," and jazz arrangements of traditional Jewish music. (Note: just a few of many possible links.)
There are numerous artists in many genres doing some really interesting stuff with Jewish melodies. I'm not even including the incredible body of new original Jewish music that's out there.
The Jewish music scene is much larger than the "Hasidisco" coming out of Brooklyn and Israel.
