One of the founding fathers of rocksteady, Delroy Wilson was a key figure in the early development of reggae in the ‘60s, injecting a patient, warm vocal delivery into the genre that felt like a close cousin to American soul music. As producers slowed down the herky-jerky rhythms of ska and smoothed out the lower end, Wilson stayed in the pocket, providing measured, unhurried vocals on classics like "Conquer Me" and "Dancing Mood" that owed as much to Sam Cooke as Lee Perry. "Have Some Mercy" showcases his ability to carefully glide over a track, with Wilson filling in the empty spaces of the song with nimble melodic filigrees.
