Got a nice promo package from Lucky Break, a bluegrass band who are blending Shabbat Zemirot with Appalachian music. Check out "Kee Eshmerah Shabbat!"
Following in the footsteps of Andy Statman, Margot Leverett and the Klezmer Mountain Boys, and others, Lucky Break brings a sweet down home approach to Jewish music.
There seems to be a bit of a Jewish Bluegrass scene developing these days. It'll be interesting to see what it produces.
