The Optimo DJ/producer goes old skool in this live mix.

Glasgow’s Numbers will celebrate its tenth anniversary tonight in London. The loaded line-up includes Hudson Mohawke, Jackmaster, Spencer, Redinho, Joy Orbison, Optimo, and more.

To prepare you for tonight’s festivities, Optimo’s JD Twitch has shared this hour-long mix of ’92 hardcore, recorded live at Glasglow’s Sub Club back in 2009. And while Optimo won’t be playing rave tonight, we have been assured that a secret guest will.

Stream/download the set below. No surprise here, but Numbers was just named one of FACT’s best labels of 2013.
