  Exceptional. We tried a few people before we came to Daniel. And always felt like a big newspaper being smashed through a tiny letter box. This dude however packed us nice, kept us out the rain and gave us a phenomenal master. 10/10

  Como músico siempre trabajo para encontrar el mejor sonido para mis temas, y con Daniel la experiencia y el proceso ha sido excelente, además de sacar un sonido mejor de lo que esperaba en mi nuevo lanzamiento. Sin duda volveré a trabajar con él para los siguientes lanzamientos. Un excelente profesional
