London-born Benjamin Clementine spent time homeless and busking in Paris, and his voice betrays an urgency to stop passers-by in their tracks. Rich, dramatic and magnetic, it’s the centrepiece of his debut album. Sparsely accompanied by piano, restrained drums and occasional strings, it would be a blunt tool without the swooping melodies and poetic lyricism of “London” and “Cornerstone” however, and impish approaches to rhythm and song-shape augment Clementine’s arresting talent.
