MARACATU MEETS DJENT
Born on June 26, 1981 in Campo Bom, Brazil, Demétrius Locks has achieved global recognition for his highly innovative and technical playing style. By applying complex, heavy Brazilian grooves like Maracatu to double-bass drumming, he created a signature style that captivated drum legends worldwide.
Whether headlining European Drum Camps alongside Dom Famularo, leading clinic workshops at the prestigious Musicians Institute (MI) in Los Angeles, or holding down the rhythm for Vitalism—the biggest progressive Djent band in Brazil—Demétrius delivers mind-blowing complexity with uncompromising artistic energy.
