I came to know that Sri D Pasupati passed away recently while checking out the forums on rasikas.org. He is not widely known, but very well known within the Kalakshetra community as he had spend a good amount of time at Kalakshetra, Chennai. The obituary in The Hindu was very well written leaving little scope for others to say more about him.
I have always enjoyed listening to a couple of his recordings (one concert and an assorted collection), that Sri Kulkarni generously shared with me quite a while ago. Some of the compositions that you can listen to in the tracks below are rarely heard and his style of rendering these compositions makes them even more special.
First a full concert at Kalakshetra:
You can hear a detailed introduction of him at the start of the concert.
