Overview
Rock entered the Brazilian music scene in 1956, with the screening of the film The Blackboard Jungle, featuring Bill Haley's "Rock Around the Clock", which would later be covered in Portuguese by Nora Ney.
The electric guitar was already used in Brazil in 1948, in Salvador carnival bloc of Dodô e Osmar. They invented the famous "pau elétrico" (English: "electric stick"), the first electric guitar without microphonic feedback, with its typical acute color characteristic and sustained sound, no more similar to the previous jazzistic electric guitar models (then they developed another with two arms) and in 1949 they played carnival songs with this guitar at the first time in an open car named then "Trio Elétrico" on the Salvador streets (today in the big trucks with a very robust sound).
