Mr. K with two slices of Philadelphia disco, from smooth and slinky on our A-side to all-out floor pounding disco madness on the B.

Janice McClain, rightly adored for her Garage classic “Smack Dab In The Middle” (feat. on MXMRK-2068) but her second single is a real under-the-radar treat. The comfortably laid back groove somewhere between a stepper and simmering midtempo disco, classy and danceable as the finest Philly soul. Originally on a small LA-based label in 1983 (and sounding like it could have come out a good five years earlier), written and produced by McClain’s uncle Milt Tennant and his writing partner Thom Page, the same team responsible for “Smack Dab” — all Philadelphia rooted, so the sound should come as no surprise. Add McClain’s heartfelt and uplifting vocal and we easily have a lost classic. Mr. K’s edit trims the rare 12-inch version down for maximum sonic fidelity for its first appearance in a 7-inch format.

The flip side vibe goes in a completely different direction, although once again has its roots in Philly. The disco remake of the standard “Brazil” was a massive hit for the Ritchie Family in 1975, topping Billboard’s dance charts and getting deep into the Top 20 on the Hot 100. The group itself was a studio concoction led by veteran producer Richie Rome, with legendary trio Sweethearts of Sigma handling vocals — you’ll recognize their trademark harmonies from other huge classics like “Ain’t No Stoppin’ Us Now” and “Love Is The Message", studious listeners will detect a lot of similarities in the vamp section of “Brazil” and “Love Is…” as the MFSB house band launches into their trademark groove. This vamp section is unfortunately truncated on the original 7-inch single, but the always-attentive ear of Mr. K picks this point to begin his edit, starting where the original single faded out and giving us a full four-plus minutes of galloping disco delight.
