Ra Cailum has been played on NTS shows including NTS Guide to…, with Seven Daze A Weed first played on 5 June 2025.

Ra Cailum is the synthpop/chillwave music project crafted by the Saint Louis, Missouri, based artist, Anthony Engelhardt, who also goes by the moniker PIRATES OF THE CARIBBEAN II AND III. Engelhardt's musical undertaking through Ra Cailum began in 2009 as a bedroom hobby in his Saint Louis home. Since then, it has transfigured from beat-filled House/IDM electronica to intelligently formed synthpop with clear new wave and ambient influences.
