Duke Ellington: "There are simply two kinds of music, good music and the other kind."
And I agree with Giselle saying people enjoy good music. The Montreal Jazz Festival embraces many forms of music from around the world without boundaries. You may have Stanley Clarke's jazz fusion , the world jazzy pop of Pink Martini or Quebec's own Boogie Wonder Band bringing back the funky 70's. There's something for everyone. I like to get out of my comfort zone and discover a new favorite every year.
One year my new encounter was Chantal Chamberland from Montreal- Nord. Impeccable phrasing with a voice that is the focus without being overwhelmed by the instruments. Leto - I am sure many of the lovely local French ladies would love her. Here is a lovely rendition of "La Vie en Rose". Transports me to Paris in my mind whenever I hear this.
P.S. Obvio - Wow you read my mind on Frank Sinatra. If I had to recommend two Sinatra albums, they would be In the Wee Small Hours and Songs for Swinging Lovers. But you know for me, I always loved Watertown( although not one of his more successful albums.) Sinatra also did albums with Ellington, Basie, and Jobim. He has many hidden gems but the two Obvio mentioned are the best. (Great to see someone else here appreciates Sinatra.)
