If you’re looking for a perfect document of disco as it existed right before it went from trend to craze, forget the ‘Saturday Night Fever’ soundtrack: this is how to get down. A showcase for Salsoul Records when the label was the ultimate circa-’77 seal of quality for dance music, this set assembled by DJ Walter Gibbons includes four continuous, momentous mixes on four LP sides that lay out plenty of deeper cuts (naturally, there’s a ton of great Salsoul Orchestra jams) and Paradise Garage faves (including Tom Moulton mixes of First Choice’s “Dr. Love” and Claudja Barry’s “Sweet Dynamite”). Hold on to your ass when you hit Side 4: it starts with Loleatta Holloway’s “Hit and Run” and somehow gets even more intense from there.
