|VOA Heavy Rock Festival is one of Portugal's biggest and best known festivals for hard rock and heavy metal music, taking place in the country's capital city of Lisbon.
Since the first edition a decade ago, the festival – formerly known as both Vagos Open Air and VOA Fest – has consistently showcased fan favourites and established bands from the scene.
But last summer's edition, after a year off, took things up to a new level with global superstars Slipknot and Slayer topping the bill; and with metal legends System of a Down among the headliners for the forthcoming festival there are no signs of it letting up.
