Fans of multiplatinum recording artist Josh Groban can still catch him in his Broadway debut in “Natasha, Pierre & The Great Comet of 1812.”

Last December, he announced that he would extend his run to July 2.

The new musical, which opened at the Imperial Theatre (249 West 45th Street) in New York City in mid-November last year, was inspired by a romantic passage—70 pages, in fact—from Tolstoy’s “War and Peace.” It was written by Dave Malloy, directed by Rachel Chavkin.

Groban, whose role as Pierre required singing, acting and playing several instruments, did so with aplomb. The New York Times wrote, “His acting is superb, as he all but trembles with the existential despair that courses through Pierre’s veins virtually nonstop.”

“The Great Comet” is described as “a theatrical experience like no other. Malloy’s inspired adaptation… puts audiences just inches away from Tolstoy’s brash young lovers, as they light up Moscow in an epic tale of romance and passion.”
