The Master Musicians of Joujouka Festival 4-6 June is still booking on www.joujouka.net.
Updates on flights, with European airspace opening again it is a good time to book cheap flights.
Latest crazy airfare is Ryanair Madrid to Tanger return at the time of the festival for 12 euro incl all taxes and charges. Madrid is a busy hub airport and cheap connecting flights can be found to there. Ryanair, Easyjet and Royal Air Maroc fly from several European destinations including Brussels, Madird, London, Paris etc direct to Tanger.
