One for the bucket list. Get yourself to a train station in Morocco in early June 2015. Get picked up and taken to a small village in the Rif mountains where you'll be looked after and fed by families in their homes for 3 days. The Master Musicians Of Joujouka then play their special blend of Sufi music each day and late into each night. Places limited to 50 and it's €360 all in.

There's a slightly cheaper one day version (€100) on 15-Nov-2014 tied in with the Beat Conference (17/19 Nov) in Tangier to celebrate the 100th anniversary of William Burrough's birth. The conference fee is basically B&B in the hotel plus food.
