Treddin' on Thin Ice is the debut album by UK Grime artist Wiley released on XL Recordings. It was released on 26 April 2004. The album is seen as a critical success in grime music with an enduring and influential forward facing sound. However, commercially the album did not do as well, with one single ("Wot Do U Call It", a song addressing the debate over the categorization of Grime music) making the top 40 in the UK music charts.
The album along with Dizzee Rascal's Boy in da Corner are seen as the 'blueprint' of the grime genre. Many artists have cited Treddin' on Thin Ice to be the pinnacle of grime, before Wiley began taking a slightly different direction with later works, such as the album See Clear Now (2008) - in particular the UK number 2 single "Wearing My Rolex", which takes a more dance-style approach.
