Electro house is a genre of electronic dance music characterized by heavy bass and a tempo around 130 beats per minute. The term has been used to describe the music of many DJ Mag Top 100 DJs, including Benny Benassi, Skrillex, Steve Aoki, and Deadmau5. Characteristics Simon Reynolds described electro house, as a style attributed to artists like Zedd, Erol Alkan and Bloody Beetroots. Electro-house is typified by its heavy bass. This is often in the form of buzzing basslines, such as those created with sawtooth waves and distortion. It is also often in the form of large bass drum sounds in a four-on-the-floor pattern. The tempo of electro house is usually between 125 and 135 beats per minute, usually 130. Electro house sometimes resembles tech house, but it can contain melodic elements and electro-influenced samples and synths. In contrast, Reynolds stated the genre had "little relationship with either house or electro". History Reynolds described the sound as being influenced by Discovery by Daft Punk and further developed by Justice and Digitalism. The sound was popularized in the United States by deadmau5 and noted the style's distinct style had a "dirty bass" with "grinding and whirring sawtooth b-lines". By 2011, the word "electro" had come to be seen as an adjective denoting "hard electronic dance music". Early songs that have been labelled retroactively as electro house include "Dark Invader" (1996) by Arrivers and "Raw S*it" (1997) by Basement Jaxx. Mr. Oizo's "Flat Beat" (1999) has also been considered an early example of the genre. Andy Kellman of AllMusic described "Satisfaction" (2002) by Italian DJ Benny Benassi as being a precursor to electro-house. By the mid 2000s, electro house saw an increase in popularity. In November 2006, electro house tracks "Put Your Hands Up For Detroit" by Fedde Le Grand and the D. Ramirez remix of "Yeah Yeah" by Bodyrox and Luciana held the number one and number two spots, respectively, in the UK Top 40 singles charts. Since then, electro house producers such as Feed Me, Knife Party, The M Machine, Porter Robinson, Yasutaka Nakata and Dada Life have emerged.
