About Popup. The current bio story: Popup are from Glasgow. They are Adi, Damian, Michael and Nicholas. Some might say that they’ve worked up a storm - others might say that Scottish weather is too turbulent to notice. They rehearse in a drafty old tobacco factory near the River Clyde where they sit close together to keep warm. This is how they write their songs - by sitting close together until an idea sneaks in through a crack in the wall.
