Ryan Tedder

Hailed as the Undercover King of Pop, Ryan Tedder not only became a dominant force on the charts around the globe with the anthemic arena rock of his own band, One Republic, but also helped to shape the musical landscape as a prolific songwriter for both emerging talent and established superstars. A protege of R&B visionary Timbaland, Tedder initially worked behind the scenes, penning material for the likes of t.A.T.u., Natasha Bedingfield and Jennifer Lopez, before scoring a hit alongside his mentor, "Apologize," with One Republic that thrust him into the global spotlight. The Colorado quintet subsequently became a radio staple but it was the songs that Tedder gave away to other artists which cemented his reputation as one of pop's most bankable hitmakers. With the likes of Leona Lewis' transatlantic chart-topper "Bleeding Love" and Beyonce's Grammy-winner "Halo," Tedder had developed a big beat power ballad sound that was unmistakeably his own. But later collaborations with acts as diverse as North Carolina rapper B.o.B, emo rockers Cobra Starship and synth-pop chanteuse Ellie Goulding proved that he was far from a one-trick pony.
