Zagreb's brand-new Museum of Contemporary Art building is a landmark in the life of the city, catalysing a revival of interest in art and culture. One of the most refreshing things about the museum is its healthy disregard of convention, so it's fitting that the first major international exhibition to arrive is by a pair of artists famed for blowing raspberries at polite society – in the most gentlemanly manner, of course. The immaculately besuited Gilbert & George have worked so closely since they met at London's St Martin's School of Art in 1967 that they have become a single artist, with their own figures and daily activities themselves comprising their art. This exhibition, the “Jack Freak Pictures” is so named because the Union Jack is central to their exploration of the wide world through the letterbox of their home in London’s East End, fingering attitudes to themes such as religion, identity, sexuality and death. Back in 1970s London, G&G’s were fuelling controversy mirroring that caused by the punk movement. Now in their 60s, the duo is no less conciliatory. But don’t get the idea that these two are out to shock for the sake of it. There’s a current of humanity here: the problem isn’t with religion but with dogma, the freak isn’t here to be poked fun at because we are each of us freaks to a degree. This is an exploration of humanity in all its frailty, sometimes grotesque but often endearing, and a plea to all: please accept us the way we are, as we love you complete with your paradoxes and weaknesses.
