Hi. I’m Lucas Rosen, RJSO’s director. I am excited to be with the ensemble for our second year of operations.
I recently completed my fourth year of a bachelor of music in saxophone performance and when I’m not with RJSO I spend my time playing with one of my many other bands, or working on public art events. It’s my pleasure to be back directing the band this year, I look forward to seeing you all at our concerts this year!
Right now my favourite song is “Iron Lung” by King Gizzard and the Lizard Wizard
Hey! I’m Ibrahim, I’m the founder of the Rocky Jazz String Orchestra and a third year science student at the University of Alberta.
I was born in Tartus Syria and moved to Canada in 2016. When I’m not studying, I’m writing music, or working on my medical application. You can find me volunteering at various hospitals around the city or maybe at CCIS crying over my grades, if you see me, please come say hi!
My favourite song right now is Ray’a by Amr Diab

General Advisor
wassUP, I'm Calvin! I'm a multi instrumentalist in my second year of music at MacEwan university. I've lived in Alberta my whole life just outside of Edmonton till recently. I've been an active part of the marching arts in Edmonton for a couple years now and when I'm not doing that I'm probably practicing, playing or composing somewhere around the city!
My favorite song is The chicken/soul intro off of Jaco Pastorius’s Invitation-live
Hi! I’m Nathan Heinbuch, and I’m a General Advisor (mainly helping with arrangements) for RJSO, as well as a composer, arranger, and multi-instrumentalist born and based in Edmonton, Alberta! Performing-wise, you can mainly see me as a clarinetist, trombonist, and percussionist around town, where I’ve been involved in various kinds of ensembles from marching bands to free improv groups.
Currently I’m focusing on taking my Bachelor of Music in composition at the UofA, which has helped me get closer to the music that has impacted my life since I was little, and turn all the inspiration and emotions into something of my own :)
My current favourite song is Prokofiev’s Second Piano Concerto
Hello! My name is George, and I recently joined the RJSO executive team. I was born in Winnipeg but have lived in Edmonton for 7 years. It’s here that I discovered my passion for playing the trumpet.
I’m currently a first-year Physiology student at the University of Alberta, and I hope to keep my love for music as I pursue a life in the medical field.
My favourite song right now is “The Colour Violet” by Tory Lanez.
