The interplay between vibraphonist Milt Jackson and trombonist J.J. Johnson is the main reason to acquire this set. With fine backup from pianist Tom Ranier , guitarist John Collins, bassist Ray Brown and drummer Roy McCurdy, Jackson and Johnson are in top form on a variety of bop standards, including Johnson's "Lament," "Our Delight," "Bags Groove" and "My One and Only Love." Enthusiastic, consistently swinging music from some of the best.
