One of the greatest composers in the jazz history got a most deserving and ariculate piece of attention by some of the greatest american and german jazz artists on this CD.Mahogany's vocal are often used as if he were a member of the band, rather than a vocalist star (this is reminiscent, for instance, of some of the Ellington's classical recordings). But, although the WDR band (directed by Bill Dobbins) sounds excellent on tracks without Mahogany, it is his presence that brings something special, particularly when he scats like mad (on "Pussy Cat Dues").My only serious complaint is that the tracks often end too soon after the applause, instead of more natural merging of the songs at an album. But, this is a really insignificant remark that fades in the presence of Mahogany, Jimmy Knepper, Charles McPherson and other musicians.
