“…since we’re in San Francisco, we thought we’d do something special.” Bernard Sumner, singer and guitarist for New Order, as preface to an unexpected, second encore closer and cover of “San Francisco (Be Sure to Wear Flowers in Your Hair)” at the Bill Graham Civic Auditorium last night. One of just a half dozen dates on this North American tour, the concert showed a band that has worked to refine their live set, with updated visuals as well as a bit of tweaking and reworking of what has become their usual selection of songs. It was definitely the best I’ve heard them in the past four years, and they seemed most energized during their performance of new song, “Plastic”. The sold out crowd of around 7,000 never stopped moving and bouncing as they ripped through a sequence of favorites at the end with “True Faith”, “The Perfect Kiss”, and “Blue Monday”. As has been tradition, they closed out with an encore of a few Joy Division covers, but the Scott McKenzie cover at the very end showed that they can still surprise when they are inspired to do so.
