In early 2007, local savings bank Bilbao Bizkaia Kutxa decided to become an official sponsor for the festival, as part of the actions for its 100th anniversary celebration campaign. As a result, the festival's name was changed to "Bilbao BBK Live". Unlike other sponsorship renamings, where the sponsor's name is usually dropped in an informal context, this festival is commonly referred to as "the BBK Live" or simply "the BBK". The second edition enjoyed a "significant budget rise", and the area designated for the stages and camping was also increased from 70,000 to 110,000 m2. The 2007 edition was also the first (and currently only) to be celebrated in June, a decision took based on the "European summer festival calendar". An extra date was also added, spanning two weekends, 21-22 and 28–29 June. American bands Red Hot Chili Peppers, Metallica, Incubus, New York Dolls, My Chemical Romance, and British heavy metal band Iron Maiden were among the international headliners for this edition, meanwhile local rock band Fito & Fitipaldis stood out among Spanish acts, and received the largest audience of the event. Over 95,000 people attended the event, and produced an economical impact estimated in 13 million euros.
