Influenced by the '60s surf pop of the Beach Boys and the '70s disco of ABBA, Revolucion Sexual is the third studio album from the enigmatic Spanish act la Casa Azul. Produced by Guille Milkyway, often rumored to be the solo performer on the band's material, the 2007 follow-up to Tan Simple Como el Amor includes the singles "Esta Noche Solo Cantan Para Mi" and "La Nueva Yma Sumac."
