Udi Raz heard music in his head as a young boy, long before he knew how to play or write it. He picked up the trumpet when he was 9, but it wasn't until he stumbled upon The The Dirty Dozen Brass Band's album "Watcha Gonna Do for the Rest of Your Life" that he realized exactly that. Captivated by the sound of Kirk Joseph's sousaphone playing, Udi picked up the tuba and sousaphone and found himself immersed in the vibrant world of brass band music. In 2005 he was a founding member of Marsh Dondurma, a 16-piece brass band whose energetic, uplifting music draws inspiration from diverse traditions. Within the band, where he still plays today, Udi has evolved as a musician, composer, arranger and vocalist. After many years of being fascinated with South African vocal harmonies, Udi founded הקולות הצפים (Hakolot Hatsafim), an intimate vocal group fusing harmony singing and lyrics that find beauty and meaning in small, everyday experiences. Hakolot provided Udi with an outlet to delve into more delicate and introspective aspects of musical expression. Over the years, Udi had the privilege of recording and performing as a tuba, sousaphone and trombone player alongside artists such as Berry Sakharof, Bnaya Barabi, Riff Cohen, Dudu Tassa, Hadag Nachash and The Alaev Family. He is also a former member of various bands including הפשרות (The Compromises), Hoodna Orchestra, תזמורת המהפכה (The Revolution Orchestra), We Are Ghosts and Ohana Brass Band.
