ORFIM International Music Festival
Open-air classical music festival held over about five nights in early August in the streets of the old town, with a wide programme from orchestral works and flamenco fusion to a Jazzfim jazz strand. Free, late-evening concerts you can simply wander up to.
The clever thing about ORFIM is the timing. Concerts kick off around 11pm, once the worst of the August heat has lifted and the old town has cooled into something far more pleasant. You'll find yourself on Calle San Jaime or in the square by the church, with the music drifting up between the old stone walls and no ticket to fuss over.
The programme leans classical but doesn't stay there. Across roughly five evenings you might catch a proper orchestral piece one night, a flamenco-flavoured set the next, then the Jazzfim strand bringing something looser and warmer. The players are a serious bunch, national and international names, yet the whole thing stays refreshingly informal. Wander up, find a spot, stay as long as you like. Exact dates shift each summer, so check locally nearer the time.
