This is a dangerous arena in which to work in Switzerland, where the local hard-edged, geometric art concret style is ever-present, over-composed and extremely polite. When Neo-Geo came along with its salutary critique of idealist abstraction, it was commonly misunderstood here. Artists misappropriated the name, claiming it as a rebirth of the timeless geometric abstract. But not Boetschi, which is why his work is so invigorating. In his paintings he acknowledges geometric art's tradition, but also shows that he has taken deconstructivist doubt to heart.
