The band was playing at Newbridge Road Park in Bellmore Saturday night, as part of the Town of Hempstead's 2019 Summer Concert Series.

"Mason's passion was being the band leader of 'Beginnings - The Ultimate Chicago Tribute.' This goes way beyond learning the bass parts and high vocals that he worked so hard on for every performance," the band wrote on its Facebook page. "He engaged in every email, post, phone call to every venue and its representation. Mason did all of this and more with a smile. Every 'meet and greet' after each show saw Mason shaking hands and smiling in pictures with everyone. We're on stage for 90 minutes for each show, but the countless hours he put into this band off stage to make the next show better for everyone involved are incalculable."
