You’ll probably have to special-order these dates, which were recorded in 1987 and ’88, respectively, and released on England’s Naim records, but by all means do so. Charlie Haden’s Private Collection, Nos. 1 and 2, capture the wistful and probing elegance that marks the best work of Haden’s ensemble Quartet West as well as the freshness that often results when top-notch ensembles play live. Here, the film noir quality so beloved by the leader-bassist is less studied, yet the whispered brand of swing so central to this group’s aural ideology is consistently present, especially on rarely heard titles like Tony Scott’s “Misery,” in which tenor saxophonist Ernie Watts sheds his fusionoid shackles for a lovely, unfettered foray, and Pat Metheny’s “Farmer’s Trust”—in which the composer’s and the bandleader’s Midwestern roots tastefully and lyrically mesh.
