This long, Labor Day Weekend in the United States, Brad Mehldau is in Paris for the world premiere performance of his new Piano Concerto at the Philharmonie on Saturday. After beginning the evening with a solo set, Mehldau is joined by l'Orchestre national d'Ile-de-France, led by Clark Rundell, to perform the new piece. The concert is part of the two-week Jazz à la Villette festival.

Mehldau was at Philharmonie de Paris earlier this year, performing his Three Pieces After Bach program. As with his album After Bach, released on Nonesuch in March, that solo program pairs selections from Bach's Well-Tempered Clavier with Mehldau's own works inspired by the piece. You can watch that concert in its entirety here.

Hamasyan makes stops in Nishinomiya, Nagoya, and Saga over the next week, before heading back to the States for an October tour. “As a pianist and composer,” says NPR, “he draws inspiration from jazz, folkloric and classical sources, in ways that feel both hypermodern and practically ageless.”

Gabriel Kahane joins the Oregon Symphony and conductor Carlos Kalmar for an encore performance of his new oratorio, emergency shelter intake form, at the Arlene Schnitzer Concert Hall this evening. The piece, which looks at deep poverty in America, received its world premiere with the orchestra in May. Kahane sings as part of the "chorus of inconvenient statistics"; also performing ar mezzo-soprano Alicia Hall Moran and the Maybelle Community Singers, many of whose members are currently facing extreme poverty. Tonight's concert is presented free-of-charge, with a pay-what-you-will suggested contribution and all proceeds going to a consortium of social service agencies.

Kahane discussed his just-released Nonesuch debut album, Book of Travelers, with NPR's All Things Considered, and performed songs from it on New Sounds' Soundcheck earlier this week. Rolling Stone calls the album a "stunning portrait of a singular moment in America."
