Awesome Sia

James Corden picks up another very talented passenger for a ride, with vocalist, songwriter and producer Sia singing like a badass, and providing insight into her mysterious and quirky persona.

Sia, Jimmy Fallon and The Roots cover The Dixie Cups’ acoustic rendition of the Mardi Gras song Iko Iko, with the not-so-special participation of Natalie Portman, who seems to have mellowed down from her Lonely Island days.

Electric violinist Bryson Andres turns in an impressive and unique arrangement of Sia’s powerful hit track Chandelier using a combination of live string playing and his digital loop pedal. Check out more of his tracks on YouTube.
