Ian Matthews (born 20 June 1971) is an English musician, best known as the drummer for the rock band Kasabian. Prior to Kasabian, Matthews played with a number of noted local Bristol bands, such as K-Passa, CCQ, and Sissi. He met Kasabian in 2001 before the band were signed when they were recording demos in Bristol. From these early sessions Matthews recorded with them came the single "Processed Beats". He also played on "Butcher Blues" from Kasabian's self-titled debut album. He also overdubbed an extra drum track over the single version of "Cutt Off", and recorded the drums to the B-side "Beneficial Herbs". He was asked to tour with them in April 2004 and became a permanent member in April 2005.
