2020 marks the 25th anniversary of the longest running festival in Greece. Rockwave Festival is celebrating its silver edition and has already announced two separate days in June. First up, it's two absolute legends of the game; Deep Purple and Opeth will rock the Terra Vibe stage on June 6th with more acts to be announced. British alt-rockers and Greek favourites Placebo are also part of the celebratory line-up on a different day later in June. If this news has tingled your rock and metal sensors and you're thinking of booking those tickets, may we suggest also considering a car rental as the Malakasa park is known to get pretty bottlenecked during concerts.
