Perfection. Pandit Sivakumar Sarma (also Shivkumar Sharma) was the first musician to play Indian classical music on the santur (a hammered dulcimer traditionally used as a folk instrument). Sarma has had a hugely prolific career and has worked with the most legendary classical musicians, but I have yet to hear very much of his catalog because I can’t tear myself away from this. Achingly beautiful work from the master of the instrument.
Note: Nobody seems to know exactly when this record was released, but based on a few hints I would guess mid-70s. This never made it to CD and to the best of my knowledge, has never been reissued (cough).
