Nicolaas Douwma (born 13 April 1982), better known by his stage name Sub Focus, is an English DJ, music producer, songwriter and sound engineer.

The main reason he followed this path and ultimately got more involved in it was because it meant that he could successfully create a whole song on a computer without having to be able to play a musical instrument.

His first major influences were groups such as The Prodigy and The Chemical Brothers, artists who blended guitars with dance music.

[6] "Rock It / Follow the Light" also got him a third UK Dance Chart number one, as well as reaching the B-list of BBC Radio 1's playlist.

Sub Focus has also remixed selected works of The Prodigy, deadmau5, Rusko, Dr. Octagon, Empire of the Sun and Dizzee Rascal.

In 2010, Sub Focus was a support act for Australian drum and bass band Pendulum on their UK tour to promote their third album Immersion.

It was followed by "Tidal Wave" featuring Alpines which peaked at number 12 in the UK Singles Chart, which also became his first to spend at least two weeks in the top 40.

"Tidal Wave" also featured on the Mercedes Benz "Sound with Power" advertising campaign, along with Tinie Tempah.

On 15 September 2020, Douwma announced on Twitter that a collaborative album with fellow UK artist Wilkinson would be released on 9 October of that year.

[11] The album contains 14 tracks including the singles "Vibration (One More Time)" featuring AR/CO, "Ready to Fly" with Dimension and "Off the Ground".
