"Jazz Sur Seine" is definitely one of Barney's good ones. I have a lot of Barney's discs, including many of his very-hard-to-find IDA discs. If I were to pick a favorite, it would probably be "Passione" (Venus) with some nice trumpet work by Enrico Rava. But I'm also partial to "Le Ca: New York Romance" (Venus & Sunnyside) because of the great rhythm section of Kenny Barron, Ira Coleman and Lewis Nash.
One of Barney's fans created a
website in his memory. It has a complete discography. There are a few titles in there that I've been trying to find for a few years, including "Paris Moods" with some early work by Jacky Terrasson.
