Here a beautiful cassette by Aminuddin Dagar of the Senior Dagar Brothers. Judging from the sound of the recordings it was recorded at the same time as the LP published in 1983. Bolingo posted this LP in 2011 on his wonderful blog. See here.
On the artist see:
In my shop on Discogs are still nine volumes of the "The Lyrical Tradition of Dhrupad" series, published by Makar Records, available at a good price.
