I assume it’s time for WLIW‘s spring fundraiser, for instance, because “New York Public Television” has scheduled for one evening (March 11) of prime time the smooth r&b couple Ashford and Simpson in performance at Feinstein’s at Loews Regency; photogenic trumpeter Chris Botti

performing with John Mayer, Josh Groban, Steve Tyler and the Boston Pops, and the 1959 broadcast “The Sound of Miles Davis,” featuring music from the trumpeter’s classic album Kind of Blue, now 50 years old and satisfying as ever.

This tv show, produced between the album’s two recording sessions, has kerchief-wearing Davis leading John Coltrane, Wynton Kelly, Paul Chambers and Jimmy Cobb through “So What” (but not Cannonball Adderley and Bill Evans, who also were key to the music’s success). Shot in black and white with an air of intensity and reverence, the show also includes Davis’ great friend and collaborator Gil Evans gently conducting a chamber orchestra. It has been available on various video collections for years, and of course can be viewed on YouTube, too.
