It was such a pleasure reading about your collection and setup!
On a sheer coincidence, I just read a very interesting article about Charanjit Singh and about Ten Ragas - and how it was so way ahead of its times and is probably THE pioneering album of the acid movement.
There's also a small snippet of the album song. It is interesting to observe that Bollywood was really pushing the boundary during the disco days. Anyway, I am amazed that you have this record!
