Os Jovens were a duo from Rio de Janeiro in the mid 60s. "Coração de pedra" (heart of stone) is an powerful sixties garage track. With an over-the-top organ sound, fuzz guitar and a tight beat, this song shows that Brazilian musical history has a lot more to offer then Samba, Bossa Nova and MPB. The Jovem Guarda scene, which was concentrated in Rio and São Paulo, hosted some great musicians like Roberto Carlos, Erasmo Carlos, Wanderlea, The Beat Boys and Brazilian Bitles.
