Images: I had taken them back in June and posted here.
Music: Pandit Ravi Shankar on Sitar and Ustad Alla Rakha on Tabla at Woodstock Festival of year 1969. This was their last appearance at Woodstock, it proved to be too much for them culturally. (video of their performance)
And yes, it was actually raining while they performed.
An interesting footnote: George Harrison visited Kashmir in 1966 along with Ravi Shankar to learn Sitar.
