Chambers' second studio album, "Barricades & Brickwalls", was released in September 2001 via EMI Music, which was also produced by Nash. It debuted at No. 4 in the ARIA Albums Chart and peaked at No. 1 in February of the following year. Its third single, "Not Pretty Enough" (January 2002), also peaked at No. 1 on the related ARIA Singles Chart in the same month. The track was written by Chambers and according to Australian musicologist, Ian McFarlane, "about being ignored by commercial radio." He cited her autobiography, "A Little Bird Told Me" (2011), "'I wrote [it as a song about feeling invisible... it was obvious that out in the music industry there was only one path for most young women – over-sexualised and over made up. To succeed you needed to look like Britney or Shakira."
