The independent jazz reissue label Mosaic Records garnered a rightful reputation as industry leaders and enthusiast favorites with deluxe and strictly limited-edition packages such as this one. The contents of this four-LP/three-CD collection are derived from two performances during the summer of 1954 and feature the Chet Baker Quartet: Baker (trumpet/"boom bam" percussion), Russ Freeman (piano), Carson Smith (bass), and Bob Neel (drums). The two performances – recorded July 21 at Santa Cruz's Civic Auditorium and August 10 at The Tiffany Club in Los Angeles, respectively – are presented chronologically.
