by Scott YanowThe third of Oscar Peterson's five duet albums with great trumpeters (the other encounters feature Dizzy Gillespie, Roy Eldridge, Clark Terry, and Jon Faddis) teams the masterful pianist with the great swing stylist Harry Sweets Edison. The trumpeter, who uses repetition to great degree and had pared his style down to a relatively few notes, matches well with the virtuosic Peterson on these seven standards and their two simple originals, Basie and Signify. Together Edison and O.P. give the impression that their chance-taking improvisations are completely logical and a lot easier to play than they really are.
