It might have been the mild snows in the last few years that finally persuaded theater companies to acknowledge winter as a time for people to go out, or maybe more artists willing to rehearse through the holidays.
Whatever the reasons, what is undeniable is the number of world premieres in evidence during the months when playgoers were formerly presumed to be hibernating. Here's what you can see before the vernal equinox:

Don't think that all these spanking-new shiny plays opening so early in the year means we're left with nothing but fossils for the spring. Look forward to April, when Chicago Shakespeare brings back Aaron Posner and Teller ( minus Penn ), the duo that gave us the 2015 stage-magic Tempest, to cast their spell on the Scottish Play. Double, double alakazam!
