Call it jazz, funk, soul, what you will the essence of music is communication between an artist and their audience. So when Candy Dulfer, the queen of the alto sax, invites the crowd at the 2002 Montreux Jazz Festival to "invade my personal space" and approach the stage, the message is clear it's going to be an intimate evening. A boisterous one at times, too, as the Stravinsky Auditorium is transformed into an after-hours club where the music and dancing just doesn't stop.
