Diane Warren wrote the song "Catch My Breath" for Boaventura; he had a recurring role on the Brazilian production of the television series Family Ties.

When he was 15, he purchased a Dire Straits live album, which made a tremendous impact on his music sensibilities.

With schoolmates, he formed two bands, Horas Vagas (Spare Time) and Os Tocáveis (The Touchables), while also completing courses in administration, public relations and advertising.

Baiana de Patifaria, noticed Boaventura on his stage debut, singing classic Broadway vocals.

He subsequently performed a solo show called "Pop n' Jazz," for which he won the Caymmi Trophy in the covers category and soon after took part in a production of Bertold Brecht's O Casamento do Pequeno Bourgeois (A Respectable Wedding) where he sang, acted and played saxophone.
