“We are rocking it,” said manager Nichola Walkden. “When we look at other venues, and what’s being done, we’re really proud.” Hermann’s has been raising money through its online and socially-distanced YouTube concerts since March 30, the most consistent run of any live music venue in the city. To celebrate the year that was, the club is offering a free four-hour concert featuring more than 50 artists, including Pablo Cardenas, David Vest, and Maureen Washington for those who have supported its efforts over the past several months. “This is, ‘Thank you.’ This is not, ‘We need more,’ because our supporters have already given so much,” Walkden said.
