We were driving up from Boston to Rockport, Mass. to check out an unusual show: Robin Pecknold, lead singer of the legendary folk band, Fleet Foxes, was playing a solo acoustic tour, even though he didn’t have any solo releases. The frontman would be dusting off songs he doesn’t get to play with the band very often, a handful of their hits, and some other tricks. As we drove closer to the venue, the surrounding houses only got more Cape Cod-styled.
