Coming out of the Hardcore period... 
Silvio Aquila (Arend Hebers) started listening to (hard)trance, hardhouse and techno. But then he discovered Hardstyle!

Silvio Aquila began to mix in 2003 in a local youth centre on the holy Technics turntables.

In 2006 he was asked to join a dj team consisting of 4 dj's & 1 mc, thanks to this he got a chance to present himself to the 'outside world'. Unfortunately this dj-team decided to split up and everybody went their way in 2007...

Afterwards Silvio explored more places in the the Netherlands, abroad and slowly building his reputation. In 2008 he became a resident dj of the well-known online Harder Styles radio FearFM. 

Left his mark on party's like Vroeger Was Alles Beter, Hardclassics, Back2school, Indicator, Decibel and more.These days Silvio Aquila still performs, in the Netherlands and abroad.

K. Smyllz, is a driven hip-hop artist currently based in White Plains, NY. Although living and working in the USA, he was actually born in Haiti, back in 1994, and his childhood was affected by many though hardships. At a very young age, he had to witness the murder of his cousin, and he had to struggle quite hard to fulfill some of the basic living needs that most people take for granted, such as finding food and avoid being kidnapped. His life changed dramatically in 2002, when his family moved to New York City. There, he fell in love with the local hip-hop culture, and it didn’t take long before he started writing his own dope rhymes and beats.
K. Smyllz set out to create a unique sound, inspired by some of the best rappers of his generations, ranging from Chance The Rappers and Kendrick Lamar, to Migos and Future, just to mention a few.
K. Smyllz’s sound is particularly notable due to the artist’s unique musicality and lyrical approach.
His most recent release is a forward-thinking hip-hop banger titled “Red Light”, which stands out as a phenomenal example of the artist’s creative vision.
 
The song is currently available for download on iTunes, and there is also a video on Youtube, shot by Judlin Civil. “Red Light” is rap/trap at its best, showcasing K. Smyllz’s skills and his ability to link the old school greatness with the modern punch
