Listen to Sia’s Demo of Christina Aguilera’s ‘Blank Page’

If you just can't get enough of Christina Aguilera's 'Blank Page' -- and we can understand if you feel that way, given that she's described it as 'sort of the heart' of her new album 'Lotus' -- you'll want to hear the recently unearthed demo recorded by the song's co-writer, Sia. [FYI, the full-length was taken down, so this is just a snippet, for now.]

The Australian artist, who's a singer-songwriter in her own right in addition to being a highly sought-after collaborator for artists like Flo Rida and Rihanna, co-wrote 'Blank Page' with Aguilera and producer Chris Braide. We've had a couple of months to get used to the official version, and now (thanks to the YouTube channel SlowRnBAddicts, via Oh No They Didn't) we have a chance to weigh it against Sia's recording, embedded above.

Of course, Sia isn't quite the singer Aguilera is -- most vocalists aren't -- but given that 'Blank Page' depends more on quiet emotion than rafter-rattling histrionics, that doesn't put her at too much of a disadvantage; along those same lines, the song's intimacy means it doesn't require a ton of slick production, so even though this is presumably an early demo, its arrangement and overall sonic quality don't suffer too much in comparison with Aguilera's recording. Have a listen, and see which one you prefer.
