These are old cassettes from various collections. I have digitized these from my grandfather Shri Patel Mahabalaiah‘s collections. Shri Harikrishna Holla contributed Ramachandra Navuda records. Shri Phanindnra Hegde contributed Kappekare recordings.
This is being done with a noble intention of making rare audios available to public. If you notice copyright violations, I urge that you support this cause, yet I will take them down promptly if the claims are found correct.
