A couple weeks ago a meticulously produced and packaged CD reissue of Intents and Purposes, a classic and incredibly rare 1967 album by trumpeter Bill Dixon, began turning up in record shops. International Phonograph, the Chicago label behind it, isn’t exactly new, but its only other release is an album by reedist pianist Richie Beirach and bassist George Mraz that came out in 1981, when the imprint was based in Los Angeles. Label owner Jonathan Horwich, a Chicago native, returned here in 2006 after living for four decades in the LA area, where he cofounded and ran Revelation Records—a jazz indie that released great music by the John Carter-Bobby Bradford Quartet, reedists Warne Marsh and Anthony Ortega, and big-band leader and arranger Clare Fischer.
