Peter Naughton composed Two Rivers through his tenure at the Birch Creek Music Performance Center in Door County, Wisconsin. The pastoral sounds of this charming marimba solo were inspired by the rich farmlands and rustic architecture of that stretch of land. The piece features a main, song-like melody which is embellished throughout. As the piece progresses, the harmonies supporting this melody become more and more dissonant, with the original melody restated at the end, in its original unadorned form.
