Martyn’s unique strand of bass defies easy categorisation - to his fans and admirers, it’s known simply as ‘Martyn Music.’ With a sound that has become emblematic for all that is forward thinking in dubstep Martyn pushes a defiant out-of-the-box mentality into his every artistic venture, scorning genre convention and relentlessly embracing the new. Informed by a love for Detroit techno, Chicago house and hip-hop, encountering drum & bass in its mid-90’s golden era was the catalyst for him to develop his musical ideas and begin to lay the foundations of his career as a DJ & Producer.
