This collection presents Sonny Rollins in both a quartet and pianoless trio format utilizing a combination of stellar European and American accompanying musicians. The Copenhagen '65 concert is a splendid demonstration of why Boston drummer Alan Dawson has been so respected and even revered by fellow drummers around the world. Even Sonny Rollins, notorious for his demanding standards for drummers, spoke of Dawson's work in the highest superlatives. Both concert performances feature Europe's finest bassist, the ubiquitous Niels Henning Orsted-Pedersen, who was nineteen years old for the Copenhagen '65 concert and already regarded as a jazz veteran and Europe's most in-demand bassist. This is classic Sonny Rollins from what so many writers, fellow musicians, and fans consider his classic period when he and John Coltrane were regarded as the most important saxophonists in jazz.
