The son of the Grammy show's founding producer, Pierre Cossette, has died.
John Cossette worked on the broadcast for more than 20 years.
He also was involved with the Latin Grammys, the BET Awards and the musical Million Dollar Quartet, now running in London and on Broadway.
In a statement, his widow Rita said the family appreciated "everyone's love and support."
Million Dollar Quartet, which dramatises a famous 1956 recording session attended by Elvis Presley, Johnny Cash and Jerry Lee Lewis, opened in the West End in February.
Cossette's other credits include the grand re-opening of New York's Radio City Music Hall in 1999.
Neil Portnow, president of the Recording Academy, said Cossette's "warmth, easygoing nature, passion for music and the arts and tireless dedication" were "unmatched."
"We were incredibly lucky to have benefitted from John's creative guidance and leadership but, more importantly, to have called him our friend."
Cossette is survived by his wife and two daughters. No cause of death was cited, and he was just 54.
Pierre passed on in 2009.
