Obscure US library run by jazz trumpeter Jack Millman (also known as "Johnny Kitchen") situated on 1513 N. Cahuenga Blvd. in Hollywood, and active from 1964 to at least sometime in the late 1970s (they put out ads in trade publications like the Kemp Film and Television yearbook as late as 1977). Very little is known about this library other than that Millman packaged cues from this library for commercial release on several budget record labels such as Condor out of Canada (including several library cues licensed from a number of German labels and published in the US under Holloway Music Publishers), the most notable being the psychedelic experimental LP "Bedlam", credited to simply "The Crazy People" (which uses a good excerpt from a calliope theme from the Mutel library, among other unidentified snippets).
The company also occasionally supplied incidental music for feature films, specifically the 1971 horror film "The Corpse Grinders", as well as "Tom" and "Ride the Hot Wind" (both 1973), and potentially more where they never received credit. Several of the German cues this company acquired, but never released on LP, were released as in-store background music on the Customusic and 3M Cantata labels.
