Beginning her career as a replacement for Anita O'Day in Stan Kenton's band, June Christy later came to great fame as a soloist. Her "cool" vocal style was quite influential, and she worked with many great musicians after Kenton: arranger Pete Rugolo, drummer Shelley Mann, trumpeter Maynard Ferguson and more. Day Dreams (Blue Note) compiles her non-Kenton early work, and a few solo albums - most notably her classic debut, Something Cool - are available on CD. Capitol's Spotlight On June Christy is a very good primer.
