Hi, I'm Marios Kalfas, also known as Velze. I'm a versatile music producer, sound designer, and mix engineer based in Thessaloniki, Greece. I love crossing genres—from Trap and Hip-Hop to R&B, House, and Tech House—and I thrive on crafting hard-hitting 808s, intricate hi-hat patterns, and atmospheric soundscapes in FL Studio. As an independent artist/producer, I handle everything from concept and composition to final mastering. I’ve built a catalog of 100+ ready-to-use beats and enjoy delivering radio-ready instrumentals and full vocal productions that align with current trends while pushing creative boundaries.…Hi, I'm Marios Kalfas, also known as Velze.
