Southern Ontario Marching Arts Collective (a.k.a. SO-MAC) is a Marching Arts competition and performance opportunity that is operated and owned by Corey Pearce Percussion. SO-MAC was started to provide WGI Percussion, WGI Colour Guard, and WGI Winds competitions, along with Drumline Throwdown and exhibition opportunities for local and international Marching Arts Ensembles with a strong focus on providing a positive environment for the ensembles to grow and improve along with quality, professional adjudicators to help educate, evaluate and support the growth of our ensembles. We are very excited to start our 2019 season opportunities for Cadets Canada Military Bands and Pipe and Drum Bands.


Southern Ontario Marching Arts Collective is a great addition to Corey Pearce Percussion as it will provide our ensembles a place to perform what they LOVE, to CREATE shows, and INSPIRE each other!
