Jacques and Paula Morelenbaum (husband and wife) are seasoned Brazilian musical veterans. Among other projects, they spent several years in Tom Jobim's "Banda Nova" and have worked with many other Brazilian artists. Jacques' cello playing is excellent, and he has done wonderful arrangements and orchestrations for many albums and movies.
The couple worked in a project with Jobim's son called "Quarteto Jobim" and then connected up with Japanese pianist Ryuichi Sakamoto to record and perform Jobim music, and the two official releases that are available in America, "Casa" (recorded in Jobim's studio in his house!) and "A Day in New York" are beautiful cds. The latter is available from yourmusic.com and I think you'd like it.
