The Led Zeppelin remasters continue with the release of deluxe editions of IV and Houses Of The Holy in October. To get you in the mood for swinging the Led, listen to our exclusive stream of a alternative studio take of the continent-cracking Black Dog.

As with the previous deluxe editions, both albums have been newly remastered by guitarist and producer Jimmy Page and are accompanied by a second disc of companion audio comprised entirely of unreleased music.

Among the treasures on the companion discs are Rock And Roll - Alternate Mix; The Battle Of Evermore - Mandolin/Guitar Mix From Headley Grange; The Song Remains The Same - Guitar Overdub Reference Mix; The Crunge - Rough Mix - Keys Up; and No Quarter - Rough Mix With JPJ Keyboard Overdubs - No Vocal. 

Both remastered albums are released on Friday, October 24th. Listen to an Irish exclusive stream of an alternative version of Black Dog.
