On December 9-11 the Isabella Freedman Jewish Retreat Center in Connecticut will host Blues for Challah: A Grateful Dead Shabbaton. The event’s goal is to draw together Jewish Deadheads “for a weekend including Grateful Dead inspired davenning and d’vrei torah, lectures, discussion groups, and – of course – plenty of music. Participants will be encouraged to bring their own instruments and be part of the jamming.” The event will feature Rabbi Moshe Shur and Rabbi Howard Cohen. Rabbi Shur, a Senior Associate at the Center for Jewish Studies at Queens College “was part of the late Rabbi Shlomo Carlebach’s musical circle (and) jammed with musicians including the Grateful Dead during his years living in San Francisco.” Rabbi Cohen, a graduate of the Reconstructionist Rabbinical School, is a lifelong Deadhead and currently runs Burning Bush Adventures, which leads “adventure trips that integrate Judaism and wilderness camping.”
