Concertos:     I list four pieces in this category:    "Lunar Eclipse" written for Christian Contreras, Tenor Saxophone started life as a song to a poem by Emily Dickinson.  "Viola Concerto" started life as a very early piano piece.  I tried, unsuccessfully, to orchestrated it, and several sections were stolen by other pieces.  These two, are probably not REALLY concertos.   They are probably tone poems.    The other two:  for piano and for violin are probably are more what could be called a concerto as they are multi-movement works for a virtuoso with orchestra accompaniment.
