Live, from Cain Park, it's the 2021 Tri-C JazzFest (in September) Print A signature Northeast Ohio cultural event that went virtual last year will be back in person in 2021 at a new venue. Cuyahoga Community College on Friday, May 14, announced that the Tri-C JazzFest Cleveland will return on Sept. 11 and 12 and will take place at Cain Park in Cleveland Heights. The event typically is held at Playhouse Square in the summer. The 2020 edition of JazzFest took place online due to COVID-19 restrictions. This year's two-day outdoor festival "will feature a variety of national acts performing under the covered Evans Amphitheater," Tri-C said in a news release.
