Mathijs Maas a.k.a. Re-Style was born on the 13th of March, 1986, in Middelburg, The Netherlands. He started to mix earlier forms of hardcore (nowadays known as old school and early hardcore), and at the age of 12, he made the choice to produce his own music. Re-Style debuted on Masters of Hardcore at the age of 15. He created the official anthem for the first Masters of Hardcore event in the Westfalenhallen in Dortmund, Germany. Since then, he has performed at large Electronic Dance Music festivals such as Tomorrowland, Thunderdome, Defqon.1, Dominator Festival, Intents Festival and Decibel Outdoor Festival. Re-Style has released several songs on the Masters of Hardcore record label, as well as other labels such as Roughstate, Pussy Lounge Records and Foolish Records. He has also produced official anthems for music festivals such as Harmony of Hardcore with his track "Ultimate Hardcore Feeling", Masters of Hardcore Russia with "Savage & Wild" and Masters of Hardcore Austria with "The Awakening".

In 2018, Re-Style began creating music that included aspects from the frenchcore genre. His 2009 track Get It Crackin’ was remixed by Sefa. That same year, Re-Style released a collab with Charly Lownoise called "City Streets". In March 2020, as a response to the Coronavirus pandemic and cancellation of the 25th edition of Masters of Hardcore, Re-Style performed on the official Hardcore Therapy podcast. Re-Style has placed multiple tracks in the Masters of Hardcore Top 100 with his tracks "Leap of Faith", "Hate Me", "Basshead" and Sefa's remix of "Get It Crackin."
