Although tempting, Sebastian’s father resisted the urge to name him Johann Sebastian Kelzenberg. Still, he perused the influence of Bach and attempted to learn the cello at 5, and then was chosen by the oboe at 7, where he learned the European style of playing in Brazil. He then made his performing debut at the young age of 13 in Chelan, Washington where he performed so terribly, he cried immediately and ran away in shame. Since then, Sebastian has performed and competed successfully; he was a First Prize winner for MTNA and YoungArts, was awarded the Fennel Scholarship from Interlochen and the John Mac Scholarship from the Cleveland Institute of Music among other notable achievements.

Some of his notable performances have been on King-FM live radio, solo performances with the Northwest Sinfonietta and Seattle Youth Symphony Orchestra, and most recently substitute Heckelphone and English Hornist for the Cleveland Orchestra. Sebastian is also vividly active in sharing his craft publicly with the community, as he has worked with his Reed Quintet, SLANT, to perform for audiences at the Cleveland Art Museum and recently East Academy, a Charter School in Cleveland. He also has organized and conducted several orchestras at CIM to perform the Nutcracker, and at for his junior and senior recital. In his free time, Sebastian enjoys playing pickleball, arranging music for odd ensembles, and baking.
