The Qemists are a drum and bass band from Brighton, United Kingdom signed to Ninja Tune indie record label based in London. The band consists of bassist Dan Arnold, drummer Leon Harris and guitarist Liam Black. The Qemists were originally the drummer, bassist and guitarist in a rock band where they spent a lot of time touring UK and Europe as well as spending a lot of time in the studio. During this time in the rock band in the late 1990s, they acquired an interest in drum and bass and some of the group's early efforts started to get airplay. For many years they were performing in the rock band as their day job whilst producing and DJing drum and bass at night, and this conflict of interests lead to the fusion of the two styles to form The Qemists sound that is known today. They had previously worked as live sound engineers for Basement Jaxx, Kano and Lady Sovereign.
