Thurston Moore had a late announcement to play in the "hidden" stage in Barcelona's Primavera Sound this year, that took place two weeks ago.
750 fortunate people had to queue for a reservation ticket, and enjoyed the gorgeous "hidden" environment of that stage. Sound quality was average though (difficult place).
Sure you'll appreciate that quite acceptable amateur recording of the gig,
