That's a very different kind of career, where you're juggling those two commitments.
Indeed. Justin Peck's involvement with Miami City Ballet is a case in point. Scheduling has to be one of the major concerns when you are combining a dance career with one company with a choreography gig with another company .... and when you also have to factor in the completely separate schedule of an independent orchestra.
Peck was in Miami last spring to choreography a 2-person ballet, to be performed in April 2014 (more than a year later) at a concert of the New World Symphony. The dancers he selected were Jeanette Delgado (whom he describes as "one of America's greatest ballerinas right now") and Kleber Rebello. Title is "Chutes and Ladders." Music is from Benjamin Britten's String Quartet No. 1.
Peck will be back in Miami in early March, when he will participate in a couple of the Open Barre performances at the studio in Miami Beach. (March 7-8). Then, I assume, back for the premiere on April 20th.
The following is completely OFF TOPIC, but the MCB blog has a well-produced and thoughtful 3-minute video of Peck talking about the process, including studio video as well.
