Charlie Haden has always had a penchant for roots music, including folk songs from varied traditions in the repertoire of his Liberation Music Orchestra. It's more than affectation; the bassist's musical roots are in Oklahoma, and his career began in early childhood with his family's country-music group. Those sources loom large in this inspired meeting with pianist Hank Jones over a program devoted largely to spirituals, with a few secular folk songs added in. The feelings communicated here arise from no simple reading of traditional material. It's Jones's unmatched harmonic sensitivity that often works the transformation, his close-voiced chords adding new resonance to summon the depths at which this material communicates. Haden, for his part, is as effective a soloist as he is an accompanist, spare and exacting and making full use of his huge, dark sound and powerful lower register. This is music by two masters, immersing themselves in a profound stream of American music. --Stuart Broomer
