in the early 80s a neighbor lent me a black disc by the title of Raga Malkos, played by, if i remember right, 4 brothers (can't remember their name).
i gave the disc back and some short time later he moved away and i lost sight of him.

i went to an indian store where they sold music, but they told me they did not have it.

Does anyone know anything about this that would permit me to buy it somewhere?

I believe that Raga is a bit of a generic term for a type of Indian music, so you're probably going to be out of luck.
