Recorded as a benefit for the Southern Poverty Law Center, the four-song Remedy finds Son Lux as ambitious and genre-defying as ever. “Dangerous” layers singer Ryan Lott’s fragile, expressive voice over a bed of chopped-up percussion and strings, while “Part of This” explores the glitchy, post-dubstep soul of James Blake. Most striking is “Remedy”, a reflective hymn carried by 300 crowd-sourced voices.
