Watch an orchestra play classic tracks by Paul van Dyk, Eric Prydz, Armin van Buuren, at Tomorrowland 2019

Tomorrowland celebrated its 15th anniversary with two Symphony of Unity performances this year.

Musicians from The Metropole Orchestra's Academy joined conductor Dick Brossé on stage for the live orchestral renditions of classic electronic tracks.

Prior to the performances Brossé shared that despite playing some of the world's most prestigious concert halls, "performing at Tomorrowland, the world’s most famous and most original and artistic festival, will undoubtedly be a lifelong highlight."

Among the tracks the musicians performed were trance classic 'Shivers' by Armin van Buuren, Energy 52's 'Cafe del Mar' and more contemporary tracks in the form of Eric Prydz's 'Opus' and Fisher's grammy-nominated 2018 hit, 'Losing It'.
