Classic Moods refers to a number of things -- classic songs, the classic small hard-bop group, the classic sound of jazz ballads. It's clear that Ernie Watts was out to recapture the spirit of his hero John Coltrane's exquisite Ballads, and what's surprising is how close he comes to fulfilling his goal. Working with pianist Mulgrew Miller, bassist George Mraz and drummer Jimmy Cobb, Watts recaptures the classic sound of '50s small combos without ever sounding like a stodgy revivalist. That's because he's too concerned with feeling and fresh, vital improvisations to devote himself to painstaking re-creations of the past. Every musician in the group plays with passion, even during subtle interludes, and that is what brings such standards as "In a Sentimental Mood," "Green Dolphin Street" and "'Round Midnight" to life. You may have heard these songs countless times, but they're worth hearing again in this setting.
