Glasgow's Mia Dora are responsible for the last Optimo Trax EP of 2014. This release came about after they sent the track "Un. Sub" to Twitch earlier in the year. He went nuts over it's cowbell delirium bump n' grind and it has been a constant secret weapon in his sets all year. When he found out it wasn't scheduled for release, a notion formed for Optimo Trax to put it out and a few months later the Mia Dora guys delivered three other tracks to form an EP, including a track in collaboration with long time Glasgow doyen, Mash.
