President Obama and first lady Michelle Obama honored Frankie Knuckles, the house music pioneer who died earlier this month.
In a letter dated April 17 and posted to DJ David Morales' Facebook page Tuesday, the Obamas extended their "heartfelt sympathies" to the friends and family of the late DJ/producer.
"Frankie's work helped open minds and bring people together, blending genres to capture attention and ignite our imaginations," they wrote. "He was a trailblazer in his field, and his legacy lives on in the city of Chicago and on dance floors across the globe.
"While he will be dearly missed, we trust Frankie's spirit will remain a guiding force," they continued, adding that they are "holding you all in our thoughts and prayers."
Born Francis Nicholls and dubbed the "Godfather of House," Frankie Knuckles is best remembered for dance tracks such as Your Love and The Whistle Song, and remixes of Chaka Khan, Michael Jackson and Whitney Houston.
