While looking around for something else, I came across these two videos, “The Evolution of Solo Jazz Piano, Parts 1 and 2.“ They are a look at 24 jazz pianists. Twelve are from the traditional style, and twelve are from the modern style. They were made by Bill Dobbins in 1990. All are variations on a theme based on the harmonic progressions of the standard “All of Me.” They’re well worth tucking away and dipping into from time to time.
According to an internet blurb:
Bill Dobbins is professor of jazz studies at the Eastman School of Music in Rochester, New York, where he teaches the jazz composing and arranging courses and directs the . . . Eastman Jazz Ensemble and Eastman Studio Orchestra. As a pianist, he has performed with orchestra and chamber ensembles under the direction of Louis Lane, Pierre Boulez, Lukas Foss and Frederick Fennell, and he has performed and recorded with such jazz artists as Clark Terry, Al Cohn, Red Mitchell, Phil Woods, Bill Goodwin, Gary Foster, Dave Liebman, John Goldsby and Peter Erskine. . . . From 1994 through 2002 Mr. Dobbins was principal director of the WDR Big Band in Cologne, Germany, and he headed the jazz studies department at the Hochschule für Musik in Cologne from 1998 to 2002.
