Some of the tunes are catchy and fun, but few measure up to his vast catalog. More effective is Duke's Quincy Jones-like flair for inviting too many musicians to the party and then making the most of each invitee. It's always been clear, however, that Duke is a far superior keyboardist than vocalist, and it's unfortunate that most of his best solos here come midway through vocals that don't always catch fire. Two of the all-instrumental pieces--especially the meandering ambient piece "At a Glance"--fall short, but the brassy, snappy "Whatever It Takes" keeps the focus where it should be, on his melodic playing. More of this would create the cool Duke aspired to.
