Nile Rodgers is the kind of guitarist who doesn’t just play grooves—he builds them. I first clocked him in the late ’70s with Chic, where between 1977 and 1980 he helped turn disco into something sharper, leaner, almost mechanical in its precision. Then the ’80s hit, and suddenly his fingerprints were everywhere: early ’80s work with David Bowie on "Let’s Dance", Debbie Harry’s "KooKoo", and mid-decade cuts with Cyndi Lauper. The thing is, Rodgers never overplays—he trims, tightens, locks everything into place. You hear it once, and after that, you can’t unhear it.
