Background: Skunk Anansie are a British rock band whose members include Skin (lead vocals, guitar), Cass (guitar, bass, backing vocals), Ace (guitar, backing vocals) and Mark Richardson (drums and percussion). Skunk Anansie formed on 12 February 1994, disbanded in 2001 and reformed in 2009. The name "Skunk Anansie" is taken from Akann folk tales of Anansi the spider-man of Ghana, with "Skunk" added to "make the name nastier". They have released six studio albums: Paranoid & Sunburnt (1995), Stoosh (1996), Post Orgasmic Chill (1999), Wonderlustre (2010), Black Traffic (2012) and Anarchytecture (2016); one compilation album, Smashes and Trashes (2009); and several hit singles, including "Charity", "Hedonism", "Selling Jesus" and "Weak".
Context: Mark Richardson confirmed reports that the band was reforming in an interview with Drummer Magazine (November 2008 issue), and said that the band planned to release a "best of" compilation as well as new material. Ace later set up an official page for the band on MySpace. On 2 and 3 April 2009, two shows took place at the Monto Water Rats (the former venue of the Splash Club) in London, under the alias SCAM (Skin, Cass, Ace, Mark) and sold out in 20 minutes. The band began their "Greatest Hits" tour on Friday, 9 October 2009 at the Ancienne Belgique in Brussels, with other dates across Europe. It was their first actual tour in eight years. A "greatest hits" album, Smashes and Trashes, was released 2 November 2009. It is a 15-track career-embracing album and includes three brand new tracks: "Because of You", "Tear the Place Up" and "Squander". A best-of remixes companion album was also released digitally.  On 3 July 2009, the music video for "Tear the Place Up" was presented exclusively on MySpace, before on 10 August 2009, a new video for "Because of You" was presented exclusively on Kerrang.com. It was released 14 September 2009 in the UK and was the first single to be released from Smashes and Trashes. The single was a top 10 hit in Italy, before its follow-up "Squander" was a top 75 success in Flanders, the Dutch-speaking part of Belgium.  Their fifth album Wonderlustre was released internationally on 13 September 2010, preceded by the first single "My Ugly Boy", which was released in the UK on 16 August 2010 and in Europe July/August. The video for "My Ugly Boy" was presented exclusively on Kerrang.com on 23 July 2010. Wonderlustre reached number one on the Italian albums chart on 1 October 2010 and placed in the top 10 in charts all over Europe including in Germany, the Netherlands, France and Poland.  In May 2010 they were a supporting act for Rammstein, during two concerts in Berlin. The second single from Wonderlustre, "Over the Love" was released internationally in November 2010. In November 2010 the band played on Idolos, a Portuguese equivalent to the UK's Pop Idol.  "You Saved Me", the third single from Wonderlustre was released internationally in March 2011.
