Led Zeppelin Premiere Unreleased Version of Black Dog

Yeah, baby.

As hennemusic.com reports:

Led Zeppelin are premiering an unreleased version of “Black Dog” as a preview of the upcoming expanded reissue of their 1971 release, “Led Zeppelin IV”, due on October 28.

Jimmy Page describes it for Rolling Stone Magazine:

"The version on the companion disc is a rough mix in its early stage with minimal guitar overdubs and Robert's original vocal. And you can hear how mean it is."

The "Led Zeppelin IV" deluxe edition includes unreleased versions of every song heard on the original album including alternate mixes of "Misty Mountain Hop" and "Four Sticks", as well as mixes of "The Battle Of Evermore" and "Going To California".

There's also an alternate version of "Stairway To Heaven", which lets fans hear the song long banned from music stores as they've never heard it before. :-D
