The two artists will go back-to-back at the Edinburgh party's anniversary event this Friday.
Since it first started back in 2006, Substance has been one of Edinburgh's most important outposts for house, techno and bass music, having hosted everyone from Luke Vibert to Boddika to Jeff Mills over the years. For their sixth birthday, they've booked a rare back-to-back set by two very of-the-moment artists: Blawan, the still-ascending producer behind the RA Recommended His He She & She EP (i.e. the one with "Why They Hide Their Bodies Under My Garage") and Numbers resident Jackmaster. Those two share the bill with Substance's Gavin Richardson.
Tickets to Substance 6th Birthday are available here on RA.
