Perhaps the ultimate proof of this can be seen now through Dec. 24 in the online stream of Smuin Contemporary Ballet’s “The Christmas Ballet.” Created in 1995, a year after Smuin founded the San Francisco dance company, this spectacle was designed to sate all tastes (though you’re more likely to love it if you lean toward a Rockettes-style Broadway baby aesthetic). There’s a “Classical Christmas” opening half dressed in white and set to music including Bach’s “Magnificat,” and a “Cool Christmas” second half dressed in red and set to pop ditties such as “Santa Baby” and “Christmas in New Orleans.”
