Black Sun Press: The Black Sun Press was an English language press noted for publishing the early works of many modernist writers including Hart Crane, D. H. Lawrence, Archibald MacLeish, Ernest Hemingway, Laurence Sterne, and Eugene Jolas.  It enjoyed the greatest longevity among the several expatriate presses founded in Paris during the 1920s, publishing nearly three times as many titles as did Edward Titus under his Black Manikin Press.  American expatriates living in Paris, Harry Crosby and his wife Caresse Crosby (inventor of the modern Bra) founded the press to publish their own work in April 1927 as "Éditions Narcisse".  They added to that in 1928 when they printed a limited edition of 300 numbered copies of "The Fall of the House of Usher" by Edgar Allan Poe.  They enjoyed the reception their initial work received, and decided to expand the press to serve other authors, renaming the company the Black Sun Press, following on Harry's obsession on the symbolism of the sun.

Black Sun Ensemble: Black Sun Ensemble is a Tucson, Arizona, US–based psychedelic rock band, led by Jesus Acedo that was formed in the mid-1980s.  The initial albums garnered rave reviews from Rolling Stone and several of the independent music journals of the time.  Black Sun Ensemble opened for Camper Van Beethoven on the "Key Lime Pie" tour in 1989 to appreciative audiences across North America.  Infamous circumstances surrounding their Geffen Records showcase in Los Angeles lead to the quiet intervention of Paul McCartney to get certain members and their entourage out of custody- a tarot card was involved, but any more may detail may arouse the attorneys!  (based on statements from Jesus Acedo & Duane Norman).  Additionally, the bloody death of a goat in the audience at the 1994 Burning Man festival lead to widespread public outcry and condemnation from animal rights group PETA.  The band was forced underground and splintered, reformed and fell into hiatus due to extenuating circumstances and the mental illness of Jesus Acedo.  Mickey Rourke, a close friend to Jesus Acedo at the time, was urged by friends and family to visit Acedo in his dreams embodying the dark angel, compelling him to resume writing.  This was the inspiration for the song, "Murder" (showcased on the October 29, 2015 episode of Shonda Rimes' ABC hit show How to Get Away with Murder).  Furthermore, if Mickey Rourke bestows a mood ring upon you, you take it.
