Simply Tsfat are Breselev Chassidim from the US and Canada, who now live and perform in Israel. They have a half dozen or so albums available through Sameach Music and well loved in the frum Jewish music community. I forgot to mention, I picked this video to play today because of the lovely performance of Shabbos Kadshenu. Shabbat shalom!
Hat Tip to Rabbi Doug for posting this video and lots more.
