Two years ago, Belfast's subversive and secretive street artist, Glen Molloy picked up a can of spray paint and answered the call by transforming his career as a DJ into one where his creativity comes alive while the city sleeps.

Painter, artist, activist and all-purpose creator, Glen's previous life saw the creator work as a DJ in Belfast for more than 20 years. Although seemingly fast-paced and adrenaline fuelled, Glen found this world tiring and demanding. His creativity was restricted and his passion was on lockdown. Sticking it out, simply to survive, his grayscale life didn't offer much in the way of happiness and didn't leave much time for following his dreams of a more coloured lifestyle creating masterpieces for the masses to enjoy. That was until Glen had a 'now or never' realisation.

Fed-up with the cold, harsh, perimeter of his surroundings and no longer able to resist the urge to give his city's walls life, Glen shook his spray can and shook the fear out of himself to make his mark on the city's walls. Retreating into anonymity, Glen spent two years painting distinctive, large scale portraits of iconic faces across Belfast by night. For months, mystery shrouded the inexplicable art that was springing up across the gritty Belfast Docks area.

Now unveiled as the secretive street artist behind the famous face creations, Glen has been hailed as Belfast's Bansky and is recognised as one of Northern Ireland's most influential street-artists.

Whilst he still prefers to work under the shelter of darkness, Glen embraces the public appreciation of his art and says his creations belong to the people across the city.

To those who have yet to #AnswerTheCall Glen says, "It doesn't matter when you realise what you're made to do. What's important is that you go for it."
