Sam Major was sitting in the sound booth, her fingers on the board riddled with tiny buttons that could transform a performance, when she realized that she was good at technical theatre. The booth, a hole in the wall with its door disguised by a blue and green mural, sometimes felt big with only two people inside, and sometimes felt claustrophobic with eight or nine people squeezed inside. And though Sam, then a sophomore, hadn’t spent much time in the booth, in that moment she had the most power in the theatre — she was the stage manager of Community Ensemble Theatre’s (CET) fall production of “Into The Woods.”
