James Blake returned to BBC Radio 1’s Residency tonight, and he was joined on air by Justin Vernon of Bon Iver, as Pitchfork points out. The two chatted about a number of topics, and Blake closed out the show by playing a new cover of Simon & Garfunkel’s “The Sound Of Silence,” which he dedicated to a friend who passed away on New Year’s Eve. Although he swaps out the original’s rippling guitar for his usual mournful synths, it’s a pretty minimal, faithful cover — which is good, because the original is gorgeous, and so is this. Listen below, and hear the entire mix here via the BBC.
