Legendary local festival (of Glastonbury status in Italy), televised on Rai (Italian state broadcaster, like the BBC) held in the small town of Melpignano (about 25 mins drive south of Lecce).
Free entry, extremely busy (expect a crowd in the tens of thousands) but an unmissable event for any serious muso.
Special all night train service usually runs from Lecce and Gallipoli to Melpignano.
