João Gilberto
Astrud Gilberto, who had never sung professionally before was featured on two tracks, "The Girl from Ipanema" and "Corcovado (Quiet Nights of Quiet Stars)". Like João Gilberto, Astrud Gilberto has a quiet, almost whispered vocal style which would become an important influence on female vocalists in bossa nova. On João Gilberto's first three albums—"Chega de Saudade", "O Amor, o Sorriso e a Flor" (1960) and "João Gilberto" (1961)—the vibrato in his voice is not entirely absent like on "Getz/Gilberto".
