In the late-1990s, Stalteri was a pioneer in interpretations and arrangements of Philip Glass's piano music. His album, Circles, became one of the early classics of the Glass piano repertoire. When approached by the label about an anniversary re-release of Circles, Stalteri responded with the idea to re-record, re-interpret, and re-imagine these Glass works. The title, Dodecagon, is drawn from the name of a shape with twelve sides - corresponding to the twelve tracks on the album.
