It was announced on November 22, 2014 and was available to pre-order from iTunes immediately in the USA, Canada, and Mexico.
It was also available for pre-order worldwide at midnight on Sunday, 23 November 2014.
There's also two bonus tracks, a live version of Don't Stop and Kiss Me Kiss Me as iTunes and Target exclusives respectively.
On the album, they commented:
"Playing live has been something we have been the most passionate about from the beginning. All we want is for our fans to come to the shows, rock out and have one of the best times they've ever experienced. Also when a room is full of you guys from all different walks of life, you can let it go when you come to the shows and be free to be yourself. Our live album 'LIVESOS' is now available to preorder on iTunes or our webstore in the USA, Canada & Mexico. Everywhere else can from midnight this Sunday 23 October. It has 15 tracks recorded in different venues around the world! Anyways we love you, this is us live... You rule!"
