There is just one week to go before the release of Steve Reich's Double Sextet and 2x5. Until then, you can listen to the album streaming in its entirety as an NPR First Listen. "Reich's innovations across the decades seem to have been distilled and polished to a sheen not heard in his music before now," says NPR of Double Sextet. "[W]hat makes every new Reich recording an opportunity to uncover new mysteries is his continued willingness, as with the rock idiom of 2x5, to shift gears and change direction. He makes it easy to want to follow him on a wild, joyful ride."

With AfroCubism due out in just over a month, National Geographic has an exclusive music preview, streaming the album track "Al vaivén de mi carreta." The album and band are the cover story of the October issue of Songlines. "It's a quite superb coming together of Cuban and Malian traditions to create something that sounds excitingly fresh and new," says writer Nigel Williamson. "There was a genuine creative tension between the tightly structured approach of the Cubans and the looser, more improvisational attitude of the Malians. And it's perhaps this tension that makes it such an exciting album."

Philip Selway's debut solo album, Familial, can now be heard streaming in its entirety, featured as NPR's First Listen, at npr.org. "As a member of one of the most accomplished rock bands in the world, the bar is set pretty high," says NPR's Robin Hilton. "But when you listen to the beautifully produced pieces Selway came up with on Familial, it's easy to see him not as a percussionist, but as a genuine singer-songwriter."

Punch Brothers close out a banner week with Rhapsody naming their new album, Antifogmatic, Album of the Day, calling its songs "so strong and the emotional impact of the material so direct" that they supersede their complex mix of genres.

He has met his matches in his fellow Punch Brothers," and their new album "is better than the best of all their worlds."
