Guilherme Arantes Guilherme Arantes (] ) is a Brazilian singer-songwriter and pianist. As a teenager, he was a member of the band "Os Polissonantes", which also featured Brazilian actor Kadu Moliterno on bass guitar. In 1969, Arantes started the band "Moto Perpétuo" with fellow students from USP's architecture course. It was with Moto Perpétuo that Arantes got his first taste of touring and recording in a studio. The band split up in 1974 as Arantes wanted to pursue a more commercial, pop style of music. Arantes dropped out of university to dedicate himself to his solo career, and in 1976, his song "Meu mundo e nada mais" (My world and nothing more) was picked by Rede Globo to feature in the soundtrack for the telenovela "Anjo Mau". The song was a hit, and Arantes toured the country for the first time. His first self-titled album was released the same year on Globo's Som Livre label. The song "Cuide-se bem" (Take good care) from the same record, was also picked by Globo for another telenovela, "Duas Vidas". Arantes went on to write another 23 songs for Globo's telenovelas, most of which became radio hits. Besides his solo work, he has also written songs for artists such as Gang 90 & Absurdettes, Elis Regina, Marina Lima and Maria Bethânia.
