Want to escape new-millennium stress and be transported back to the mellow, club-crawling grooves of the ’70s? Pop in this glorious musical time machine. The long-running British act (22 years and counting), with its ever-rotating lineup, revisits its soul-smacked roots under the direction of group founder Jean-Paul “Bluey” Maunick. From the throbbing dance rhythms of “Morning Sun” to the stretch-out vibes of “Byrd Plays,” Incognito’s rich fusion of jazz/ house/funk remains pleasingly intact. At the same time, while vocalists Kelli Sae, Joy Rose and the returning Joy Malcolm bring additional style to the proceedings, you still miss the oomph of Maysa Leak. This quibble aside, “Who Needs Love” makes for one very pleasant journey.—GM
