At the heart of Double Moon is a collaboration involving the complex interplay between two spirited minds. Each of Margo Klass’s box constructions is an invitation to enter among objects in space and make of them what one might. Frank Soos has taken up that invitation. Margo’s constructions and Frank’s responses talk to each other, sometimes agreeably, sometimes ironically, sometimes earnestly, and sometimes flippantly. This collection stands as a representation of five years of their aesthetic sparring. Whoever picks up this book is invited to play along.
