Query: Ancient Music From Afghanistan

An extremely intersting and valuable document. This music is the precursor of Indian Classical Music. This great master is i beleive the only great master of Rebab that has left us a modern recording. The recording is excellent and the music haunting and deep. If the preceding words have frightened you i must also add it is really enjoyable music though not for easy listening. Giorgio from italy
