This powerhouse collection of covers and originals, penned by vibraphonist Roy Ayers as well as his talented Ubiquity bandmates and recorded in Jimi Hendrix's famed Electric Ladyland Studios, aimed to put bodies in motion. Ayers elevates Bill Withers' sombre "Ain't No Sunshine" into a swinging groove; later, with a flourish of strings and gentle tempo, he emphasises the intimacy of Aretha Franklin's "Day Dreaming". That's Ayers singing and scatting on keyboardist Edwin Birdsong's fiery title track, an anthem of black liberation.
