The Duet Series is one of the few series that Martin has periodically put sculptures in over a long period of time. Starting in the early 90’s and the last two into 2008. All of them have to do with relationships. Based on different types of relationships, some long-term, some that have challenges in them, some of them Martin’s own experiences, and some of them in observing others. The passion and struggles resulting from love and relationships are the inspiration behind the Duet Series. While the sculptued characters are brilliabntly rendered, the depth of these pieces moves far beyond simple aesthetics. The narrative dramas unfolding in the series both honor and question the dynamicnature of the couple.
