Yousef & Heather recorded this Essential Mix for BBC Radio 1, first broadcast on 14 December 2003 — their only appearance in the Waveform archive. It lands in the early-2000s era of progressive sounds and superstar DJs, and the set sits in House territory.
A full tracklist for this broadcast has not been documented — the recording runs as one continuous set. It aired in a year that also brought Essential Mixes from Infusion, Audio Bullys, Dave Seaman.
