Spain is a festival country, we are a country where people from overseas come to our festivals for a different experience – summer heat means shows don’t start til 5pm. In most cases, that means you have half a day to go to the beach, museums, nice restaurants, shopping or reading books in your bed, aka having a real holiday experiencing the cities or towns all day and then dancing all night long.
Spain's festivals are unique also because of our regional diversity and also many in their artists bills, many of them need at least 40% of local talent, as Spaniards love their own bands as much as foreign ones. Once again – won't stop repeating this – we need more unity and exposure of “other” countries' amazing talent in our EU festivals where you can discover and enjoy bands from Estonia, Ukraine, Finland, Germany, Italy, France, etc. and also from Latin America, Asia, and beyond.
Regarding styles depending on the artistic direction of each festival but usually (sometimes too much) it’s lots of indie, pop and urban. I wish some would open their bookings to other sounds like soul, jazz and roots.
