Catch the closing night of Post:Ballet’s fifth season, “Five High,” tonight. Featuring ballet talents with pedigrees from far as the Paris Opera Ballet and the Dutch National Ballet to as close as Smuin Ballet and LINES, the company premieres Robert Dekkers’s ourevolution, with music by Nils Frahm and visual art by Enrique Quintero. This new work explores the modern condition of isolation and the remaining possibilities for social and environmental connection. The program also brings the return of last year’s field the present shifts, with grandiose hanging sculptures by Robert Gilson and Catherine Caldwell and an original score by Matthew Pierce that is played live for the performance. Mine is Yours, a piece on sharing in relationships originally created for the San Francisco International Arts Festival in 2012, with music by electronic composer wizard Daniel Berkman, rounds out the bill.
