Last month, the first three Led Zeppelin albums were reissued in a deluxe, remastered format. Now, reissues of the band's fourth and fifth albums—1971's Led Zeppelin IV and 1973's Houses of the Holy—have been announced. They'll be out October 28 via Atlantic/Swan Song.

As with the first three albums, the reissues of IV and Houses of the Holy were remastered by Zeppelin guitarist Jimmy Page. They'll be available in a variety of formats: CD, deluxe edition CD, vinyl, deluxe edition vinyl, digital download, and a box set that includes all of the above along with a coffee table book filled with Zeppelin ephemera and a print of the cover art.

Both reissues will come with a companion disc of bonus tracks. The IV bonus disc includes "the fabled, alternate 'Stairway to Heaven' mixed at the Sunset Sound Studio in Los Angeles," according to a press release. Check out the tracklists below.
