The Azkena Rock Festival (a.k.a. ARF) is one of the most relevant Spanish rock festivals. It is celebrated in Vitoria-Gasteiz (Álava) organized by Last Tour International. ARF is notorious due to its diverse cartel of groups and for the submerse 'chill' environment of the festival. It is aimed to underground public, escaping commercial mainstream agenda. In 2006, the festival sold over 44,000 tickets, the most in its history, due to the presence of Pearl Jam. Some other bands included Iggy & The Stooges, Wilco, Alice Cooper, Social Distortion, Tool, Queens of the Stone Age, Ray Davies, Bad Religion, Sex Pistols, Deep Purple, The Black Crowes, Hanoi Rocks, Fun Lovin Criminals, Kiss, Slash, Imelda May or Bad Brains.
