The 18th Day is the debut studio album by British singer-songwriter/rapper Estelle. The first edition was released on 18 October 2004 and the second edition on 4 April 2005. The album is almost split into two distinct styles: one half funky, UK R&B hip-hop, with the other more downbeat and soulful. Opening track "1980", the first single, contains a Wall of Sound and lyrics reminiscing about growing up. "Dance Bitch" resembles US hip hop stylings similar to Missy Elliott, while "Go Gone" has a Northern soul sound; "Free" is a bouncy funk number and also served as the second single.
