ABT: Roster in Review - 2018 in American Ballet Theatre Posted March 22, 2018 · Edited March 23, 2018 by Tapfan The fear of languishing in the corps is not a phenomenon that is unique to ABT. It's a problem for many large and even mid-sized companies. Dancers like free agents in sports, move around much more frequently than in years past. And some like powerhouse soloist Derek Dunn formerly of Houston Ballet, now dancing with Boston Ballet, don't necessarily leave because they are unhappy, but because they want other challenges. Also, I believe as surely as the president loves to tweet, that there are pockets of talent, administrative and programming mediocrity that exist in practically all of the so-called prestige companies. The concept of unyielding artistic brilliance or even uniform excellence is a largely a myth.
