There was some doubt as to whether this year's Eolica Festival would take place. However, a date has been confirmed, and althought the event will only take place on one day rather than the usual two, it's still definitely one for the must-do list.Celebrating the whole concept of renewable energy (hence its venue - the wind farm and renewable energy centre in Granadilla), the event has become one of the most respected and well-attended festivals on Tenerife's music calendar. Over 20,000 attended last year to take in the 20 hours of international music performed on four stages.Expect plenty of environmental activities, workshops and exhibitions, plus house, techno and chillout music from Teenage Fan Club, Cat People, Oxia, Telephunken DJ, Dennis Ferrer, Mathias Kaden, Drummer, Dangerbeat, Billy Flux, Marvel Hill and a whole host of others.Tickets cost €25 are available from www.ticktackticket.com, www.corteingles.es or by calling 902 150 025 and 902 400 222
