The confirmed event
The Indian Express reported KK's death in Kolkata on May 31, 2022 after a concert at Nazrul Mancha. It identified him as Krishnakumar Kunnath and recorded his age as 53. Initial reporting about symptoms and suspected causes should not be substituted for a definitive medical finding, so this remembrance does not make a new diagnosis or assign responsibility for his death.

The report recalled his work across several Indian languages. A playback recording, a film scene and a live concert are different settings for an artist's voice: screen actors, songwriters and composers contribute alongside the singer, while concert performance presents the artist directly to an audience.
The Lata Mangeshkar guide explains that playback tradition in another generation. This article does not reproduce lyrics or claim an exhaustive discography. It preserves the date behind the older link and directs readers toward current Music coverage for later reporting and tributes.
