The song premiered on Tunstall's YouTube channel on 9 July 2010 with a non-official video taken from the documentary "How to Make a Tiger Suit" (available in the Deluxe Edition of the album).
The song's called "Push That Knot Away" - it's a signature track on the album for me, as it was one of my first attempts at mixing a picked acoustic tune with electronica.
Love KT" As Push That Knot Away was available online, the song was used as a background in all of the promotional videos of Tiger Suit, and started being played live.
The song features on Tunstall's Live in London March 2011 album On 15 July, Rolling Stone magazine said that with the release of "Push That Knot Away", "the Scottish songstress ditches coffee-shop-flavored folk for a big dose of booming beats, electro textures and fuzzed-out bass", stating that "it's nice to hear Tunstall stepping out of her comfort zone: "Push That Knot Away" is a rousing, foot-stomping anthem".
However, they think that, lyrically, "Tunstall is still mired in confessional singer-songwriter clichés that are better suited for a therapist's office."
