Efecto Mariposa were formed in 1997 when Susana Alva (acoustic guitar, voice), Frasco G. Ridgeway (bass, voice), and Raúl Osuna traveled by train from their native Malaga to Madrid, chasing down dreams of a career in music. Joined by Alfredo Baón (drums), the band spent the next four years writing material, developing a sound, and creating a network through its performances. The band's self-titled debut created significant buzz among Spanish acoustic rock fans, laying the groundwork for the band's solidly successful follow-up, Metamorfosis. Efecto Mariposa decided to produce, record, and even finance their third release, 2005's Complejidad. The band's fourth album, Vivo en Vivo, appeared in 2007. ~ Evan C. Gutierrez
