Summit Music Hall owner Mike Barsch says he spent three years shopping for sound systems, "trying to set us apart from the rest," before going with an Italian GTO C-12, the Ferrari of rock-venue sound systems, last fall. The Summit often hosts well-known '80s and '90s punk, metal and new-wave bands that need massive, loud and clear sound that fits their style but doesn't send fans at the relatively intimate 1,000-seat hall running for the doors. Becoming the first venue in America to install a GTO C-12, which is popular in Europe, was a no-brainer for Barsch. "The feedback has been great," he says. "People are like, 'I've seen this band 100 times and never heard them sound this good.' They're all blown away. Word is spreading."
