In 1973 DJ Kool Herc who was a Jamaican-American, introduced a new technique that eventually resulted in the hip-hop music of later years. He used bass heavy speakers and would play and spin two copies of the same records on two separate individual turntables.The music was generally electronic and was played in different ways depending on the innovativeness and creativity of the DJ at the rave. The late 1980s is when the type of music known as acid house was created using a bass line generator, Roland TB-303. This bass line generator and inventiveness of DJ Pierre would lead to the creation of so called “acid tracks” which were later played by DJ Pierre at his raves. This was the start of a new era in which the DJ and the inventiveness of the DJ started to be appreciated by the audience at raves and dance clubs. These parties soon spread to the UK where they were promptly banned by the authorities because of the tendency for people at the parties to take illegal drugs. The parties were still held but went underground as raves.
The popularity of acid house music really took off in the late 80s in the UK, but did become subject to criticism because of the drug use. Four DJs brought ideas of how to play music after visiting Ibiza. There four notable DJs were: Johnny Walker, Paul Oakenfold, Danny Rampling, and Nicky Holloway. They were heavily influenced by the methods of DJ Alfredo who combined music from several genres including pop and funk and including acid tracks. They were able to integrate these ideas into their own DJ music. In the 1990s it became harder for DJs to organize and work at raves as laws became tougher due to the perceived drug use at such events. At about this time, the DJs brought in bass and drums into the music to produce a darker sound. The reality was this was first introduced by DJ Kool Herc back in 1973, but only became popular some time later, particularly by Krust, Roni Size and Dj Die. Clifford Joseph Price, a DJ also known as Goldie really made a big impact in the UK with his jungle beat sound.
The electronic techno sound first started in the UK with the UK DJs and then later started to become more popular in the US with such DJs as DJ Scotto who held the first rave in New York City at what was then called Studio 54. Other DJs including: Moby, DJ Frankie Bones and Rozalla, also performed live at Studio 54.
All the different influences and DJs really influenced music over time, and today some of these same ideas and styles have entered into mainstream music that is recorded and sold.
