Just over a year ago, the “Godfather of House Music” Frankie Knuckles passed away suddenly. To honor his memory, BBC Radio One included some previously unreleased material from the legendary DJ and producer in their Essential Mixes series. The two mixes that were included were both recorded in 2011, one as a part the Shoreditch Music Festival, and another in the studio.

The mixes are full of Knuckles’ trademark jubilant, soulful house sounds. Get your groove on (sorry, but old-school slang seems the most apt for such a classic dude) now via BBC’s iPlayer.
