It is hard to say best in a lifetime of listening to music in multiple genres but among my most memorable:
James Taylor sitting in my student union in 1970 on his way to perform at Cornell’s spring fling… no one had ever heard of him but he jumped out of a white van and said to the assembled less than multitudes: Hi, my name is James Taylor and I would like to sing some songs
Carly Simon making her debut at the Bitter End in Greenwich Village making her club debut on the same bill as Lily Tomlin who was the bigger draw
Roberta Flack at Lincoln Center
Santana at the Fillmore East
Pablo Casals concert in Spain, stage seating with student admission
Many performances of Alvin Ailey - Revelations over many years
Luis & Maria from Sesame Street at the Tilles Center when she was 4 years old- her first concert
BSO at Tanglewood evening performance with John Williams conducting at Tanglewood on Parade summer of 2002
Paolo Szot singing The Star Spangled Banner for those us watching Opening Night of the Met in Times Square, he was the host
Wynton Marsalis Orchestra, Jazz at Lincoln Center last winter
NY Phil … many performances over the years but Beethoven’s 5th with the new incoming conductor, Japp Van Sweden last Fall
Candide, Madam Butterfly, and La Boheme with the NYC Opera
Anna Nebtrenko in Anna Boleyna at the Met
and so on including all my daughter’s performances in middle school, high school, all-state, college and post-college including the Muppet/Jim Henson celebration in Carnegie Hall as part of Essential Voices chorus
And so many memorable Broadway moments including seeing Audra McDonald in every show she has appeared in
