Earlier this year Numero Group released Ultra-High Frequencies: The Chicago Party, a compilation tribute to the local Saturday-night UHF program. Filmed at a south-side nightclub called the CopHerBox II, The Chicago Party only aired in 1982, and the folks at Numero Group pulled the best scenes from the show’s 23-episode run for a 100-minute DVD “mixtape,” most of which features ambitious Chicago soul and disco groups looking for a chance to shine. The DVD also comes with a double-LP (or single CD) of some of the best bands to appear on The Chicago Party, and the compilation starts with Jesus Wayne’s uplifting, groove-centric theme to the show, which is today’s 12 O’Clock Track. Tomorrow night the Promontory hosts a Chicago Party screening at 7 PM with show cohost and CopHerBox owner Willie Woods and several of the musicians who appeared on the program in attendance. Woods and a handful of musicians appeared at the last screening of Numero’s Chicago Party DVD at the Chopin Theatre back in March, and hearing their reactions to the charming, decades-old footage made the viewing experience feel like, well, a party. Prepare for the screening by listening to Wayne’s theme below and take a peek at the trailer for the Chicago Party DVD while you’re at it.
