Phosphorescent’s Matthew Houck went barefoot for this year’s One Day Without Shoes, an annual event that raises awareness about the plight of children in developing countries led by TOMS, for two performances filmed by La Blogothèque’s “A Take Away Show.” The first take, a stunning electric guitar-backed version of “My Dove, My Lamb” in Houck’s Brooklyn rehearsal space, is above. He also performed “At Death, A Proclamation,” which is worth watching — if only to admire Houck’s impressive rooftop balancing act.
