This is my entry for the forum's summer competition.
The 4 pieces in the suite are based on the following abstract expressionist art:
'Vir Heroicus Sublimis' by Barnett Newman https://www.moma.org/collection/works/79250
'Autumn Rhythm' by Jackson Pollock http://www.metmuseum.org/toah/works-of-art/57.92/
'PH-129' by Clyfford Still https://clyffordstillmuseum.org/object/ph-129/
'Landscape at Stanton Street' by Willem de Kooning http://www.tate.org.uk/art/artworks/kooning-landscape-at-stanton-street-p77158
Here are the score-videos for each the pieces.
