With the arrival this week of the eminent Yusef Lateef, Ph.D. at the Keyboard Lounge of one Dr. Baker, it is only fitting that we explore the term that Dr. Lateef has used to describe his music: "auto-physiopsyrhic." "Auto-physio-psychic" music is music that comes from the mental, physical, and spiritual planes-combining the energies from each source into a music which, by definition, is mostly improvised. Yusef says that he prefers this term to the word "jazz," which can be considered a derogatory reference. He points out that the Webster's Dictionary defines jazz as "that which is discordant and noisy." "That has nothing to do with my music," he explains. We couldn't agree more wholeheartedly. Yes, Yusef Lateef is back in town at Baker's, blowing his saxophone and topping our list of musical attractions for a full ten days (14-24). You may have to go on a weekday night to get a seat, because the hipsters know that Lateef keeps a joint jumpin', an.d it's jammed on the weekends . . . Speaking of jammed, there's the Earth, Wind & Fire concert at EMU's Bowen Field House in Ypsilanti. Sunday the 17th is the night, if there are any tickets left. Ifnot, there is plenty of other stuff to keep you busy . . . John Klemmer brings his magie saxophfme to musically ten the Ramona Theatre on Gratiot and McNichols in Detroit. Singer songwriterguitarist Joan Armatrading joins him for the grand festivities, Tuesday Oct. 19. Vocalist Eddie Jefferson and drummerband leader Roy Brooks have tfiings cooking again. This time they've got the Artistic Truth band and dancer Paul Leonaid in what is shaping up to be a contemporary jazz revue at the usually-bluesy el's Lounge on the east side.
