NPR Music reports that Columbia is releasing Tell Tale Signs—Volume 8 of the Bob Dylan Bootleg Series—on October 7. (Click here for full streaming audio.) The new two-disc album chronicles a period of resurgence for the poet laureate of rock 'n roll, involving several excellent bands, lots of lovely wordplay, and a tasteful minimum of proselytization.

Previous entries in the (thoroughly official and hardly bootleg) series include the 1966 Royal Albert Hall Concert (Judas, anyone?), Live 1975 (which documents the Rolling Thunder Tour), and the soundtrack from Martin Scorsese's No Direction Home.

So what's new in this iteration? Much over which to rejoice, in fact. Besides offering a far crisper sound than any of the previous seven volumes, Tell Tale Signs features solid alt-takes from Oh, Mercy ("Most of the Time" and "Everything Is Broken," especially), some fun David Bromberg and Ralph Stanley collaborations, two (two!) versions of "Mississippi" (a neat little unreleased tune left in the wake of Time Out of Mind), and a jivin' live version of "Cocaine Blues."

Listen below to "Dreamin' of You," the pre-release single also available for free download here.
