Korean American crooner John Park went from wowing American Idol judges with his soulful voice to becoming a household name in South Korea through another televised singing competition, Superstar K2. Like the artists he's covered on both shows (including John Mayer and J.Y. Park), Park's songs lean more toward R&B than traditional ballads. Smooth, gentle tunes like “Falling” and “Thought of You” show off his heart-fluttering falsetto and stable lower end, while his natural charisma shines through on more dramatic tracks like “U.”
