1998's RAY OF LIGHT marked Madonna's move toward electronica, and a larger journey back to her dance-club roots. That journey was completed with 2005's CONFESSIONS ON A DANCEFLOOR. A collection of hardcore club tracks with few mainstream pop concessions, CONFESSIONS is packed wall-to-wall with driving, electronica-driven grooves.

Madonna has always been one of the reigning queens of postmodern alchemy, and this record is a perfect example of her magic. A primary layer of sleek, old-school disco is combined with pile-driving house and techno, not to mention more than a few contemporary production flourishes. Either directly or indirectly, CONFESSIONS references '70s and early-'80s dance music, including Madonna's own, but while the album seems retro in several areas, it also has a distinct futuristic sheen. Nothing here has the hook-heavy single status of "Material Girl" or "Like A Prayer," but the pulsing intensity of the tracks is sheer sonic pleasure, making Madonna's return to straight-up dance music a welcome homecoming.
