This little-known CD from the Spanish Fresh Sound label is a reissue of an LP from the defunct Catalyst company. The music consists of one of tenorman Paul Gonsalves' best sets as a leader. Gonsalves and trumpeter Willie Cook are heard featured in Argentina (during a tour by Duke Ellington's Orchestra) with a local rhythm section led by the fine pianist Enrique Villegas. Highlights of this fine mainstream swing set include a nearly ten-minute version of "Perdido," "St. Louis Blues" and "Just Friends."
