Martijn Gerard Garritsen, learned to play guitar at age 8. At that early age, his parents bought him a little music mixing table which he would use to entertain family and friends. In 2004, he expressed interest in becoming a DJ after seeing Tiësto perform at the Olympic games in Athens. He took particular inspiration from the track "Traffic", prompting him to download specialist software, FL Studio, and enabling him to start composing. His friends always remember how Martin used to stay at home composing with his computer while they were messing around. It was a 24/7 for him. In 2013, he graduated from the Herman Brood Academy, a production school in Utrecht. Garrix ghost writes tracks for other artists, and despite this, only one in fifty of his tracks have made it out to the public. In an interview when asked about his social class, Garrix said middle-class.He also said his 'dream mentor' was Calvin Harris.
