It was a hot night. And it was a hotter ticket. On July 18th Sum Studios opened its doors to over 300 guests to celebrate its official grand opening, marked in the day with some ribbon cutting by the Mayor of Sheffield. By the time the sun went down, we were sipping on mini-milk bottle sized pina coladas, nibbling on school dinner-inspired treats, raiding the tuck shop and dancing away to a the Desperate Sound System’s school disco.
