I cannot find widely documented, reliable information about an artist or band specifically named "Victor Mendivil, Oscar Maydon." If these are individual musicians or collaborators not broadly covered in public music reference sources, only minimal verifiable facts are appropriate: their names suggest Hispanic or Latin American origin, but without clear documentation of their country, genre, period of activity, or stylistic characteristics it would be speculative to assert details. If you can provide additional context—such as recordings, affiliated acts, or a region—they can be described more accurately based on verifiable information.
