The world of music is mourning the death of the man known as the Godfather of House Music.
Frankie Knuckles passed away late Monday at the age of 59.
His cause of death was not announced.
A native of the Bronx, the Grammy winner later moved to Chicago, where he became a key figure in the development of House music in the 1980s.
Knuckles became a premier club DJ and producer, pioneering the art of remixing.
He went on to produce music for Michael Jackson and Diana Ross.
In 2005, he was inducted into the Dance Music Hall of Fame.
