For a decade now, my routine on the 4th of July has been consistent: a family cookout late in the afternoon and then in front of the TV to see the Boston Pops perform at the Esplanade. For several years, I’d been slowly growing disenchanted by the evolution of that concert into a nationwide made-for-TV event. This year, the networks pulled out and left it an all-Boston affair. I thought it was much improved. Solo performances by Susan Tedeschi, Ellis Hall, Howie Day and Ayla Brown were all good and highlighted talent with local roots and the full rendition of the 1812 Overture with the synchronization of music, cannon fire, church bells and fireworks was spectacular. It’s not for everyone, but for those who enjoy watching the Boston Pops on Independence Day, this first rendition of the event’s newest phase was encouraging.
