Pet Shop Boys, Constitution Hall, Saturday, Oct. 14, 8 p.m.

This duo is the sound of an entire decade in Great Britain, having made the pop Top 40 with 38 different tunes in that era. Theirs’ is what could be best called “synthesized pop,” a vibrant, upbeat sound that is a step forward from disco. Around since the mid-1980s, they did the soundtrack to the acclaimed film, “The Crying Game,” among many other achievements. Their cover of the 1970s Village People song, “Go West,” symbolized the early 1990s hope and optimism of the liberated East Bloc, especially among millions of its young people. They also represented a “stiff upper” in the darkest hours of the AIDS epidemic. They’re a cultural force of no mean significance, and a very fun show. Good tickets are still available through Ticketmaster.
