Bassline (sometimes referred to as bassline house or 4x4 or niche) is a genre of electronic dance music that originated in South Yorkshire in the early 2000s. Stylistically it comprises a four-to-the-floor beat with a tempo of around 135–142 beats per minute and a heavy bass, similar to speed garage, with chopped up R&B and Pop vocal samples and a pop music aesthetic. Particularly in the scene's early days, the most prominent bassline club was Sheffield's Niche Nightclub, which became the centre of controversy due to a police raid which resulted in the club's closure in 2005.
