Review: Few contemporary jazz songwriters have emerged with such demonstrative authenticity and clarity as Gregory Porter. Liquid Spirit continues where the prolific artist left us with Be Good and Water; soulful, funky and galvanised in honest emotion. Echoing foundation-setting singers such as Isaac Hayes, Curtis Mayfield and even further back to the likes of Sammy Davis Junior, Porter flings us from vibe to vibe with precision-written lyrics and emphatic delivery. Highlights include the double-bass slapping stomper "Liquid Spirit", the boogie-fuelled "The In Crowd", the Cullum-esque "When Love Was King" and the tear-jerking finale "Water Under Bridges." Beautiful business.
