Summercase was a two-day music festival held simultaneously in Barcelona and Madrid. The schedules were the same but reverted. The line up mainly consists of indie rock, electronic music and indie pop. Hence, the festival tries to blend indie pop, rock music and dance music into one. The first edition of the festival was organized in July 2006, with a total public of over 60,000, and the second edition was celebrated on 13 & 14 July 2007, attracting over 109,000. In only one year, the festival has become one of the most important ones of Europe and falls into the category of world-famous music festivals such as the Denmark's Roskilde Festival, the Dutch Pinkpop, Ireland's Oxegen, the Spanish International Music Festival of Benicàssim or the major festivals in the UK: T in the Park, Reading Festival, Leeds Festival, the V Festival and Glastonbury Festival and may be compared to California's Coachella Festival or Chicago's Lollapalooza.

The Dandy Warhols are an American psychedelic/alternative rock band, formed in Portland, Oregon, in 1994 by singer-guitarist Courtney Taylor-Taylor and guitarist Peter Holmström. They were later joined by keyboardist Zia McCabe and drummer Eric Hedford. Hedford left in 1998 and was replaced by Taylor-Taylor's cousin Brent DeBoer. The band's name is a play on the name of American pop artist Andy Warhol.
