Since the release of her critically acclaimed second studio album, “Punisher,” in June 2020, Phoebe Bridgers has had a busy year. From her four Grammy nominations to her controversial Saturday Night Live performance, Bridgers has generated more commercial success than your average quiet, melancholic indie folk singer-songwriter. To top it all off, Bridgers is ending 2021 by going on her first tour since the beginning of the pandemic. On Sept. 27, I had the privilege of attending the second night of her performance at Boston’s Leader Bank Pavilion. While her low-key musical style may not seem particularly well-suited for a venue that seats a few thousand, she gave a generally fantastic performance that captivated the audience.
