Since the beginning of 2022, Lonnie Holley has been preparing for three solo shows: two currently on view at Dallas Contemporary and Edel Assanti in London, and one opening next month at Blum and Poe in Los Angeles. Holley also spent several weeks in February in rural England composing a new song cycle, “The Edge of What,” for Artangel. Timed to the Edel Assanti opening, Holley staged a one-night performance of the music at London’s Stone Nest last month. (Artangel also made a 25-minute film of the artist at work at the Orford Ness nature reserve, a former military testing site on the Suffolk coast.)
