Country/pop music star Taylor Swift took Los Angeles' Staples Center by storm on Monday (August 19) at the first of four consecutive sold-out nights of her "Red World Tour" at the West Coast venue. Among treating the over 15,000 fans with live renditions of her most popular songs, Taylo also had a couple of surprise moments in store for fans. There were live duets with; first, Cher Lloyd, with whom she rocked her only US hit to date, "Want You Back", and second, Sara Bareilles, performing together with her, the song that inspired Katy Perry's "Roar", the anthemic, piano-driven "Brave".
