"Rare Groove Spectrum, Vol. 3" is heaven in musical form to those who receive solace in obscure rhythms. The fine selection of reworks of classics by Lance Ferguson demonstrates his command of the groove and dedication to 70's Jazz-Funk tradition. Press play and you'll feel like you're floating on a cloud driven by the groovy influence of labels such as Blue Note, CTI and Flying Dutchman. My favorite: the Latin rework of Eddie Harris's "Losalamitoslatinfunklovesong".
