Costa Teguise has an open-air amphitheatre right above Las Cucharas beach, and for one evening each June the Casa-Museo del Timple fills it with music from across the Atlantic. The sound leans Macaronesian, which is a fancy way of saying it pulls together the islands and coasts off this corner of the world: Canarian rhythms, Galician folk with its bagpipes and fiddles, and threads from further out. Past line-ups have run from Entre Ilhas to a Celtic band, brass and percussion outfits, so the mood shifts from gentle to foot-stamping as the night goes on.
It's free, it's by the sea, and you'll likely catch the last of the sunset over the water before the stage lights take over. The date moves year to year, so check ahead before you build an evening around it.
