Ed Rush & Optical recorded this Essential Mix for BBC Radio 1, first broadcast on 2 July 1999 — their only appearance in the Waveform archive. It lands in the late-nineties peak of superclub culture, and the set sits in Drum & Bass 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 Dope Smugglaz, Judge Jules, Pete Tong.
