A talent from an impossibly young age, Chicago producer and DJ Ron Trent began his musical career aged 14, the year he produced the febrile, wild Chicago anthem "Altered States". His production output has barely let up since, minting numerous labels and sublabels to release his and other's music, most notably Prescription Records, which helped define the smoky and jazz-indebted sound of deep house in the 1990s. This In Focus is a two and a half hour dancefloor session, exploring the sounds of one of Chicago house's most enduring talents. Compiled, mixed and edited by Giles Smith.
