Bob Dylan’s new album shall be released one week early as a free online stream on National Public Radio’s Web site. NPR Music will stream the entire two-CD, Tell Tale Signs, beginning at 12:01 a.m. EDT Tuesday. It will be available for listening at least until Oct. 7, when the album is officially released by Columbia Records.

Tell Tale Signs is the eighth volume of Dylan’s ongoing rarities compilations, titled the Bootleg Series. This edition includes out-takes and rare cuts from the last two decades. An alternate version of Mississippi – a song from 2001’s Love and Theft – was earlier made available as a free download at Amazon.com.

The early album stream is a first for NPR Music, which often provides live concerts for free as podcasts.
