Joe Segal, who would have turned 100 on April 24, recorded 8- to-10,000 shows at his own Jazz Showcase and other Chicago clubs. In 2011, “Jazz Detective” Zev Feldman began visiting Segal and exploring his vast archive. Joe Segal died in 2020, but Feldman continued to work with Segal’s son, current Jazz Showcase owner Wayne Segal, and on Record Store Day, live-at-the-Jazz-Showcase albums were released from Joe Henderson, Ahmad Jamal, Yusef Lateef and Mal Waldron, plus an earlier Segal-recorded performance from Terry Callier. Feldman here describes the archive, the tapes’ condition (reel-to-reel? cassettes?), the recordings’ quality and why a digital step was used to prepare them for release. He also discusses why these performances were chosen for release first and what else is in store. And he tells how he wound up with 11 Record Store Day releases this year, including acclaimed ones by Freddie King and Buster Williams. (Photo by Zak Shelby-Szyszko)
