A criminally overlooked P-Funk treasure from 1981, Tighten It Up captures Chicago’s funk underground at its raw, electric best — with none other than Frankie Knuckles contributing as mixing consultant, giving the record an unmistakable dance-floor edge ahead of the house era. Long out of print and increasingly hard to find, this beautifully remastered RSD edition brings the Gold Coast classic back into circulation, this time on a Transparent red vinyl with restored artwork. An essential 2026 pick that shines a light on a missing link between P-Funk, disco, and early Chicago club culture — exactly the kind of deep, collector-grade rediscovery Record Store Day was made for. 1xLP, Picture Sleeve, Remastered, Transparent Red Vinyl.
