Cerys Matthews and Jeffrey Boakye are joined by saxophonist Jess Gillam and conductor Jeremy Summerly to select the next five tracks for Add to Playlist. We travel from Colombia and Brazil to the Grand Canyon, with tracks that feature astonishing vocal dexterity.

Speaking of the voice, we hear from another familiar Welsh singing legend who can tell us more about one particular note that famously proved a challenge for him in the 1960s.
