RAWBRASSTRUMPETS was established in Portland, OR by trumpet player and enthusiast Ben Zagrean. As a young child Ben fell in love with the trumpet in his born country of Romania. His parents and family permanently relocated to the United States of America. Ben was only 10 years old. He went on to study Music and Dental Technology. The extreme precision of the dental field turned out to be a huge blessing later in the trumpet shop. Ben tried to satisfy his love for the trumpet with a busy teaching schedule, conducting or writing music but it did not suffice. Ben finaly left his Dental job and started what is now know as RBT. First as a customizing shop and now as a established trumpet brand. His commitment to sound quality, precision and customer service quickly got the RBT horns into the hands of today’s top trumpet players. Some of our clients include the legendary Dr, Arturo Sandoval, Ashlin Parker (TrumpetMafia), Farnell Newton (Othership Connection), Chris Cigolea (CIG School of Arts), Dwight Adams, Russ Liquid, Ivan Jackson (Brasstracks), Joshua Trinidad, Max Ribner, Julian Gosin, Tony Glausi and many others.
