Joel Caskey - Battery

Hey! I'm from Murphysboro, Illinois where I started studying percussion back in 1999. Since then, I have continued to study and pursue music as a passion and degree. I've been in so many ensembles that I've lost count; I participated in ensembles in elementary, middle, and high school as well as for my undergraduate degree in college. While at Murphysboro I participated in marching, jazz, concert ensembles first as a student and later as an instructor. I attended Southern Illinois University Edwardsville and graduated with a bachelor's degree in Music Business while minoring in Music composition; Digital Studies and Social Sciences; Business Administration; and English Literature. I have spent a collective 7 years as a front ensemble & battery instructor in both Murphysboro and Carterville, Illinois. Additionally, I have performed in several orchestras, including the Symphony Orchestra in Paducah, Kentucky.

2023 will be Joel's 3rd year teaching the WHS Band!
