One question I've always been interested in is what bossa nova recordings came out in Brazil before Bossa Nova became popular in the US (via Stan Getz and Charlie Byrd). I managed to find a Brazilian website (in Portuguese) dedicated to Jobim that revealed that many of Jobim's most famous compositions first appeared on Brazilian LPs by a number of other artists the most well known of whom is João Gilberto. On these LPs Jobim acts as composer, side-man and sometimes even arranger/musical director
