They developed the sound of Detroit techno and in 1985 Atkins released one of the primary definitive techno tracks, No UFO’s. This sound became more popular which caught on especially around Europe in the 80s and 90s. Kevin Saunderson’s Big City and Good Life were highly successful around the world and launched techno out of the underground. The techno sound began to be adopted around the world and this spawned various subgenres. Techno can typically be identified by the use of early synthesisers and drum machines such as the Korg SQD1 and Roland TB-303 which will be used to create a repeating bassline and drum pattern, over which a synth melody or sample may be added. The music is also around 120-150 bpm and in a simple 4/4 time signature.
