Led Zeppelin has now prepared reissues of Led Zeppelin IV (the third best-selling album in U.S. history) and Houses Of The Holy, following on from the successful reissue campaign of Led Zeppelin, Led Zeppelin II, and Led Zeppelin III earlier this year. As with the previous deluxe editions, both Led Zeppelin IV and Houses Of The Holy 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 related to that album.
