A towering figure with a powerful voice to match, British singer/songwriter Seal is responsible for some of pop's most soulful hits. His undulating, world-gone-mad chronicle “Crazy”, from his 1991 self-titled debut, balances beauty and anxiety to arresting effect; the splendour of the strings and oboe in “Kiss from a Rose” provides a lush backdrop for his balladry; and the gospel-tinged devotional “Waiting for You” shows how he can channel joy into a powerhouse vocal performance. He's also deft with the classics, as his feather-light covers of canonical tracks like “Let's Stay Together” show.
