Kasabian (/kəˈseɪbiən/ kə-SAY-bee-ən) are an English rock band formed in Leicester in 1997. The band's original members consisted of vocalist Tom Meighan, guitarist and vocalist Sergio Pizzorno, guitarist Christopher Karloff, and bassist Chris Edwards. The band's line-up was completed by drummer Ian Matthews in 2004 after a string of session drummers. Jay Mehler joined as touring lead guitarist in 2006. Mehler left the band for Liam Gallagher's Beady Eye in 2013. Kasabian are often seen as one of the best British bands of the 21st century and, in 2010, won the Q Award for 'Best Act in the World Today'. They are well-known for being commended for their live performances, being named 'Best Live Band' at the award ceremonies on numerous occasions. The band's music is often described as "indie rock", but Pizzorno has said he "hates indie bands" and does not feel Kasabian fit into that category.

Kasabian have released five studio albums – Kasabian (2004), Empire (2006), West Ryder Pauper Lunatic Asylum (2009), Velociraptor! (2011), and 48:13 (2014). The band's music has been described as a mix between The Stone Roses and Primal Scream with the swagger of Oasis. Their music has won them several awards and recognition in the media, including a Brit Award in 2010 for Best British Group, and their live performances are generally lauded, the most notable of which was their appearance as headliners at the 2014 Glastonbury Festival.
