Pedro Henrique "Kiko" Loureiro (born 16 June 1972) is a Brazilian heavy metal guitarist, best known as a member of the bands Angra and Megadeth. Along with Angra's other guitarist and primary songwriter Rafael Bittencourt, Loureiro has appeared on all of the band's releases.
Loureiro began studying music and playing acoustic guitar at age 11. He studied with two big famous Brazilian musicians: Pedro Bueno and Mozart Mello. Inspired by various artists, mainly Eddie Van Halen, Jimmy Page, Jimi Hendrix, and Randy Rhoads, he moved to the electric guitar at 13 and by 16 had already joined two bands, Legalize (with Edu Mello on vocals, Dennis Belik on bass and Alja on drums) and A Chave, and was playing in nightclubs in São Paulo. At 19, he helped co-found Brazilian power metal band Angra, with whom he still plays.
Due to the increase in popularity of power metal, Loureiro has become quite successful, both playing in Angra and as a solo artist.
