I was never aware of his concert on liberation of Bangladesh, until I found a video tape in a rental video shop in Tokyo, it was back in `86/`87. I enjoed that video and later baught a CD of him in `90 performing with famous tabla or Shanai is it? musician named Allah Rkha of a concert held in London.
It is because his effort to our liberation, I always looked any news of him with reat interest, sadly now he is gone. May God rest his soul in peace.
