Thanks for those views of the Carnegie Music Hall, Pittsburgh - and I'm glad you enjoyed the Ravi Shankar concert. I've attended a few Ravi Shankar concerts - several here in India, one in the USA while I was in grad school there.
Ravi Shankar (RS) passed on in 2012, leaving behind a truly astonishing musical legacy - in Indian music as well as in 'fusion' music: Ravi Shankar, while being one of the truly great sitar players of all time, was a many faceted talent.
He was also a wonderful composer; he collaborated with diverse musicians across the musical spectrum, Indian classical; Western classical, pop, jazz (Yehudi Menuhin; George Harrison, John Coltrane, amongst others). Ravi Shankar's is a wonderful instance of 'musical talent running in families':
RS's brother, Uday Shankar was a great dancer. One of RS's daughters, Anoushka, is a 'more-than-accomplished' sitar player herself - and you've probably heard of another daughter, Nora Jones, who has made her mark in Western music, even winning Grammies, etc! (I believe RS and Anoushka too have won their own Grammy awards).
