NYT has a story on a recently-found piece by Ravel, to be premiered tonight by the NYP.

A photo of the score indicates it has trombones in it.

The conductor Gustavo Dudamel has premiered dozens of pieces in his career.

But the score that he was giddily studying on a recent afternoon at Lincoln Center was different: a nearly 125-year-old piece by the French composer Maurice Ravel that had only recently surfaced in a Paris library.

“Imagine more than 100 years later discovering a small, beautiful jewel,” Dudamel, the incoming music and artistic director of the New York Philharmonic, said in an interview at David Geffen Hall. “It’s precious.”

On Thursday, Dudamel and the Philharmonic will give the world premiere of the five-minute piece as part of a program celebrating the 150th birthday of Ravel, one of the leading composers of the 20th century, whose works include “Boléro,” “Le Tombeau de Couperin” and “La Valse.”

The photo also shows some cross rhythms. Very curious to hear it eventually.
