DJing is a craft. It reveals itself over time rather than all at once, and few embody that better than OK Williams. Active since 2019, the London DJ has built a reputation through steady accumulation rather than acceleration, becoming one of the city's most trusted and widely admired selectors in the process. Williams has never been interested in narrowing her taste into a single calling card, and it's no coincidence that her roots lie at NTS Radio. She learned to DJ at the Hackney station, starting out as a volunteer producer in 2017. Musically, she moves easily between moods—sometimes cheeky, sometimes deep—and tempos, playing everything from 160 BPM jungle and amapiano to baile funk, deep house and dub techno. For her RA Mix, Williams offers up her "purist" side. Despite her background in radio, Williams doesn't share mixes often and RA.1019 arrives as a relatively rare studio document. Recorded at home on vinyl, the 90-minute session mostly leans into '90s and early '00s techno and prog house. "Ten years ago I tried learning how to play [vinyl] on a friend's 1210s and gave up after a couple of weeks,"Williams tells us below. "Those same decks were then gifted to me years later and were used to record this mix. It's quite nice to see how far I've come." In returning to vinyl, and to the decks that once marked a rocky start, Williams' RA Mix arrives as a fitting marker for the year's end. As 2026 approaches and new resolutions begin to crowd the horizon, RA.1019 serves as a welcome reminder that the best things seldom arrive in a hurry.
