After the thundering success of their first two albums, Led Zeppelin showed that they had more than just a heavy metal side. Led Zeppelin III has an acoustic based, earthy sound and in most places finds the band in a mellow mood. “Immigrant Song” opens the album with a driving kick that belies what will follow. “Friends” and “Celebration Day” show off Jimmy Page’s skills on the acoustic guitar while retaining the power of their electric work. “Since I’ve Been Loving You” is a mournful blues dirge in which Robert Plant bleeds his heart out all over the song. John Bonham contributes the fine “Out On The Tiles”. “Gallow’s Pole” starts with a slow beat and then builds and builds and picks up speed like water rising in a dam. The water keeps getting higher and then tension builds in the song before it comes bursting free at the end. “Tangerine” is beautiful song that doesn’t get many mentions as a great Zep song, but despite its seeming subtlety, it one of the most intricate of their songs and one of their all-time best. III is among the most critically bashed of their albums, but the acoustic nature of it was a precursor to the Unplugged albums of the 90’s and the album deserves alot more credit than it gets.
