Tuesdays at HopMonk Sebastopol are vibrant and free, thanks to Open Mic with Ceni in the Abbey. This weekly event showcases incredible local talent and offers a platform for up-and-coming acts. Many bands have formed during these sessions, with Ceni fostering a respectful and supportive musical community. The first Tuesday of each month is particularly special, as it is dedicated to musicians seeking to join or form new bands.
