Triple J Live at the Wireless - Big Day Out 2011 is a live EP by Australian singer-songwriter Sia, released in 2011. Recorded at the Big Day Out festival and associated with Triple J's Live at the Wireless series, it presents her art-pop and soul-influenced vocal style in piano-driven arrangements with subtle electronic elements, reflecting a stage-focused document from a transitional period between her indie-alternative output and later pop-oriented work.
