Today's J-Deal is the "Diaspora Live on Mt. Zion" video plus Avraham Rosenblum's last album, "Kedem."
Avraham's son Mo sent me the video a while back, and it's been on my review pile for a while. The video documents the Diaspora Yeshiva Band at its peak. Well worth it for historical value, especially if you're interested in Jewish roots music with a folk/rock esthetic.
