“There’s something really cool in the air tonight,” Shania Twain said near the end of her concert Thursday night at Staples Center, and that was certainly one way to put it.

Things began to go sideways right from the start of this glittery two-hour show, part of Twain’s first tour in over a decade. In the 1990s, the singer was one of country’s biggest acts; hits like “You’re Still the One” and the title track from her most recent studio album, 2002’s “Up!,” made her a pop star across all genres: an approachable glamazon dispensing cheerful pragmatism in tunes that weren’t afraid of club beats or hard-rock guitars.
