PHOTO PROVIDED Blackberry Smoke. A Southern rock bonanza featuring Blackberry Smoke and two locally grown shows are the first to be added to the summer season at Constellation Brands-Marvin Sands Performing Arts Center. With coronavirus pandemic concerns dictating the arc of the summer season, the venue’s mainstage will also play host to a COVID-19 vaccination clinic. CMAC is also requiring proof of vaccination to attend these shows. The summer concert season opens with the traditional, Sousa-filled Fourth of July holiday special on July 3, at 8 p.m., with the Rochester Philharmonic Orchestra. William Waldrop will conduct the patriotic evening. CMAC and Thompson Health will be hosting a June 10 clinic at 3 p.m. to get the single-dose Johnson & Johnson vaccine, with registration at cmacevents.com. That will get you two tickets to the second show of the season, a “Welcome Back to CMAC Community Concert” at 5:30 pm on July 10, honoring all first responders (proof of your first responder status gets you in free).
