Here we post a private CD with two great singers of the Darbhanga Gharana. By Siyaram Tiwari we had posted already a couple of recordings. See here. By Bidur (Vidur) Mallik we had up to now only one recording from a broadcast by WDR.
On Bidur (Vidur) Mallik see:
The recordings here are presented as "A Doordarshan Presentation". Doordarshan is the Indian state television. But the recordings sound more like concert recordings.
The CD was never published. It seems that an Indian collector made out of these recordings from unknown sources a private CD and created covers for it. This person seems to take a great pleasure in creating covers and to let them look like real ultra rare releases. Which is sort of funny. And looks nice.
I received these recordings from an Indian collector based in the US. Many many thanks to him for his kindness to share these.
