Jimmy Page's job remastering the first three Led Zeppelin albums earned the guitarist/producer high marks. Round two of his labor features expanded editions of Led Zeppelin IV and Houses Of The Holy. As was the case with the previous reissues, each copy of the next two includes a bonus disc of previously unreleased material recorded during the original album sessions. Bonus material on the October 28 re-release of IV include alternate versions or mixes of Black Dog, Rock and Roll, The Battle Of Evermore, Stairway To Heaven, Misty Mountain Hop, Four Sticks, Going To California and When The Levee Breaks. The Added disc for Houses Of The Holy serves-up The Song Remains The Same, The Rain Song (without piano), Over The Hills And Far Away, The Crunge, Dancing Days, No Quarter (instrumental), and The Ocean. Super Deluxe editions will include a 180-gram vinly pressing of the album, a HD download of all of the audio and an 80 page hard-cover book of rare photos.
