"[1] He purchased some turntables and connected them to his mixer practicing his DJing, while simultaneously making music in FL Studio, a digital audio workstation.

[2] Rebergen began sending demos out to labels under the alias Nasty D-Tuners, a duo project he formed with close friend Bobby van Putten.

In 2005, a year and a half after their performance at Defqon 2004, Nasty D-Tuners were signed to Hardcontrol Records having two successful releases, with their work being played by then major hardstyle producers/DJs.

Rebergen found his time at the academy frustrating, due to a lack of encouragement towards producing hardstyle and negative responses to the genre as a whole.

[3] Alienated by his experience at the Academy, Rebergen continued to send out Nasty D-Tuners demos to respective labels, one eventually reaching Scantraxx founder, Dov Elkabas (The Prophet).

"The Sacrifice" was the duo's most successful hit to date, Rebergen since stating his fond memories of the positive reception that The Prophet gave him the first time he heard it.

[3] Problems soon began to emerge when Rebergen came to the conclusion that he would be unable to perform and record for Scantraxx while simultaneously completing his course at the Rock Academy.

Rebergen told van Putten of his decision to leave the Academy and hoped he would join and commit himself to Headhunterz and Scantraxx.

van Putten then made the difficult decision to leave Rebergen, Scantraxx and Headhunterz and continue with his musical studies at the Rock Academy.

The Prophet continued to nurture the young talent, inviting Headhunterz to perform alongside him at the popular annual Q-Dance event, Qlimax.

[3] The album debuted at Defqon.1 2008, and was officially released shortly after on both CD and digital formats on 25 July with Dutch graphical designer Ruud van Eijk providing the artwork.

Project One contained tracks such as "Life Beyond Earth", "The Art of Creation", "The Story Unfolds", "Best of Both Worlds" and "Fantasy or Reality" all proving to be successes on the dance floor.

Speaking about the moment, Headhunterz stated that he achieved one of his long-term goals within Hardstyle that night and felt "complete happiness".

Gaining inspiration from older Hardstyle DJ, Zenith, the track was a break from recent Headhunterz work with its emphasis on Reverse bass and simple scratching sounds from vinyl.

The duo making multiple appearances at the final editions of "Transmission", a popular music event that was held in Sydney and Brisbane.

[6] 2010 reflected Headhunterz and Hardstyle's growing popularity around the world, in his own words 2010 was "a year where my international bookings overtook my national ones.

The Album release was followed by a world tour visiting The United States, Australia, Russia, Canada and many performances across the Netherlands.

[9] For the second year in a row, Headhunterz was asked to make a Defqon.1 Anthem, this time for the Australian edition, "Save Your Scrap for Victory".

"The Message Is Hardstyle" had a mixed reception, many disliking the track due its soft kicks and perceived ironic lyrics given the nature of the song.

The track "Make it Loud (Headhunterz Remix)" popular for its reverse bass intro, also finally gained a release on Blutonium Records.

The 10 track album was the culmination of work done in 2011 and Headhunterz donated all profits to Dance4Life, an international initiative that mobilises and unite young people (13–19 years old) to push back the spread of HIV/AIDS.

[18] Other highlights were the early hardstyle inspired, "Back In the Days", the 2012 Hardbass Anthem, "Eternalize" and a collaboration with Psyko Punkz, "Disrespect".

Two remixes for German House producer, Zedd, "Spectrum" was released for free through Headhunterz's social media and "Clarity (Feat.

"World of Madness" was released on 16 August with the intro of the song featuring elements of the three previous Defqon.1 Anthems that the three had produced consecutively, "Scrap Attack" in 2009 by Headhunterz, "No Time To Waste" in 2010 by Wildstylez and "Unite" in 2011 by Noisecontrollers.

Speaking on his signing, Headhunterz stated: The deal with Ultra Music is a turning point in my career as an artist and producer.

The track was launched in November by Ultra Music in partnership with DoSomething.org, a non-profit organization with the goal of motivating young people to take action around social changes, with a campaign focusing on the problems of cyberbullying.

Not connected to Ultra, the label focuses on promoting the harder styles of dance music from both established artists and new, fresh talent.

We want to sign singles, no options, no commitments other than artists giving us great music we love and we push, no agenda, no-nonsense, no bullshit.

[27] At Ultra Music Festival in Miami, Steve Aoki invites Headhunterz on stage to premiere their collaboration, yet to be released.

[38] The label is described as "a dynamic platform where years of experience, friendship, talent and passion come together and spark new inspiration on the pursuit for quality and greatness in music."
