New Music Friday: The best albums out Sept. 20 : All Songs Considered

NPR Music’s Daoud Tyler-Ameen and Lars Gotrich provide a guide the most exciting new releases out today. This week, the selections include some recordings that are new and some that are as much as a half-century old, verging on mythological. The producer Jamie xx began his career as a teenager making beats for the moody electronic band The xx. His solo recordings, including the new album In Waves, have tapped into a higher energy and a wider range of sounds. The saxophonist Nubya Garcia’s new album, Odyssey, is as adventurous as the title sounds. And the Kansas City-based Blackstarkids swing between electronic pop, hip-hop and indie rock sounds that feel like they stepped off a time machine directly from the 1990s. Plus: A pair of releases that package previously unreleased material by Bob Dylan and Galaxie 500 sparks a conversation about bootlegs, alternate versions and other rare and unreleased favorites.
