Two songs into Thursday’s Fleetwood Mac concert, Stevie Nicks related a conversation she once had with her mother. What could she do to help, Nicks asked, in hard times? Her mother’s response: Sing. A simplistic solution, perhaps, but mere days after the Marathon bombing (and hours before the chaotic manhunt for the suspects would shut the city down), 2½ hours of music seemed to serve the near-sellout TD Garden crowd just fine.
In that time, Fleetwood Mac (who swing back around to the Comcast Center on June 21) covered quite a bit of ground: hits, a told-you-so segment focused on the once-misunderstood/now-cultishly-adored “Tusk,” a song that so predated Nicks’s and Lindsey Buckingham’s Mac days that they’d forgotten about it until stumbling across the demo on YouTube and a new song. And more hits. So many hits.
