I cannot find well-documented, widely known public information about a musical artist or band named "Vikram Sarkar." If Vikram Sarkar is an emerging or local musician, or a contributor in a niche scene, reliable encyclopedic details such as established country of origin, clear genre classification, or a documented period of activity are not broadly available in mainstream music references. If you can provide additional context or confirm alternative name spellings, I can produce a concise encyclopedic-style entry based on verifiable facts.
