Since 2001, he has lead his own ensemble, Noertker's Moxie, as a forum for compositions inspired by visual artists such as Paul Klee, Wassily Kandinsky, Franz Marc, Salvador Dalí, and Joan Miró, architect Antoni Gaudí, poet Rainer Maria Rilke, sculptor David Beck, and others. Noertker has composed over 175 pieces of music for this group and has released eleven CDs, including three volumes of his extended suite Sketches of Catalonia, three volumes of his extended Blue Rider Suite, and two volumes of his druidh series.

He has also composed music for three films that showcase the intimately-scaled sculptures of David Beck, composed the score for a Nikos Koumoundouros film that screened at the Festival de Cannes 2010, and most recently scored the Olympia Stone film “Curious Worlds: the Art and Imagination of David Beck.”
