Pianist Christopher Taylor, an associate music prof at the University of Wisconsin, performs the Goldberg Variations on Friday at the University of Chicago. An opportunity to see the Goldbergs is always a treat, and Taylor is an outstanding pianist – his performance of Messiaen’s complete, immensely challenging “Vingt Regards sur l’Enfant-Jésus,” one of his specialties, last year as part of the Messiaen Festival was one of the most remarkable shows I’ve ever seen.
