My guess is that this is the Glenn Gould clip that sent Jessica Williams into a new phase (see the first paragraph of the previous exhibit). It’s from the documentary Art Of Piano. Gould is at home, fairly early in his career, working out on the Bach “Partita # 2.”





The nonagenarian pianist presented de Barros with every biographer’s hope, unrestricted access to his subject’s personal papers and nearly unrestricted access to her private thoughts. He made the most of it, turning exhaustive research and hundreds of hours of interviews into a true story with the sweep of a novel. From the early discovery of McPartland’s musical gift through her wartime service, her ecstatic and stormy marriage to Jimmy McPartland, her growth as a pianist, her deep affair with Joe Morello, and the radio show that made her a national figure, she has had a fascinating life. It makes a splendid read.
Mulligan’s Concert Jazz Band had three fewer musicians than most big jazz outfits. Its size permitted precision, flexibility and subtlety, yet the band had the power of sprung steel. In this concert from a half century ago, the CJB is as fresh as yesterday. Arrangements by Mulligan, Bob Brookmeyer, Al Cohn and Johnny Mandel set standards to which big band writers still aspire. Bassist Buddy Clark and drummer Mel Lewis inspired Mulligan, Brookmeyer, Conte Candoli, Gene Quill and Zoot Sims to some of the best soloing of their careers. This beautifully produced issue of the complete concert is a basic repertoire item.
Thanks for posting this glimpse of his practice methods. I noticed that when the third voice enters with the fugue subject in the bass, he articulates the first four or five notes differently–slightly more legato than in upper and middle voices–and he maintains this distinction through the piece. And good lord, is he really doing that final trill with fingers 4 and 5? I can’t see clearly enough to be certain but if so, zowie!
I believe the word I’m looking for here is “wow.”
