Robert Anthony Plant, (born 20 August 1948) is an English singer and songwriter best known as the vocalist and lyricist of the rock band Led Zeppelin. He has also had a successful solo career. In 2007, Plant released Raising Sand, an album produced by T-Bone Burnettwith American bluegrass soprano Alison Krauss, which won the 2009 Grammy Award for Album of the Year at the 51st Grammy Awards.

With a career spanning more than 40 years, Plant is regarded as one of the most significant singers in the history of rock music, and has influenced contemporaries and later singers such as Freddie Mercury and Axl Rose.In 2006, heavy metal magazine Hit Parader named Plant the "Greatest Metal Vocalist of All Time". In 2009, Plant was voted "the greatest voice in rock" in a poll conducted by Planet Rock. In 2011, a Rolling Stone readers' pick placed Plant in first place of the magazine's "Best Lead Singers of All Time".

After the break-up of Led Zeppelin in 1980 (following the death of John Bonham), Plant briefly considered abandoning music to pursue a career as a teacher in the Rudolph Steiner education system; going so far as to be accepted for teacher-training. He nevertheless embarked on a successful solo career beginning with Pictures at Eleven in 1982, followed by 1983's The Principle of Moments. Popular tracks from this period include "Big Log" (a Top 20 hit in 1983), "In the Mood" (1983), "Little by Little" (from 1985's Shaken 'n' Stirred), "Far Post" (originally only on the B-side of "Burning Down One Side" but popularised by airplay on album-oriented rock stations), "Tall Cool One" (a No. 25 hit off 1988's Now and Zen) and "I Believe" (from 1993's Fate of Nations), another song written for and dedicated to his late son, Karac. In 1984, Plant formed a short-lived all-star group with Jimmy Page and Jeff Beck called The Honeydrippers, who had a No. 3 hit with a remake of the Phil Phillips' tune, "Sea of Love" and a followup hit with a cover of Roy Brown's "Rockin' at Midnight". Although Plant avoided performing Led Zeppelin songs through much of this period (he occasionally would improvise his unique Zeppelin screams into his set), his tours in 1983 (with drummer Phil Collins) and 1985 were very successful, often performing to sold-out arena-sized venues.

Through the 1980s and 1990s, Plant co-wrote three solo albums with keyboardist/songwriter Phil Johnstone. Now and Zen, Manic Nirvana, and Fate of Nations (featuring Moya Brennan ofClannad). It was Johnstone who talked Plant into playing Led Zeppelin songs in his live shows, something Plant had resisted, not wanting to be forever known as "the former Led Zeppelin vocalist."

Although Led Zeppelin split in 1980, Plant and Page occasionally collaborated on various projects, including The Honeydrippers: Volume One album in 1984. In the spring 2 years later Robert performed at the Birmingham Heart Beat Charity Concert 1986. The pair again worked together in the studio on the 1988 Page solo effort, Outrider, and in the same year Page contributed to Plant's album Now and Zen. Also, on 15 May 1988 Plant appeared with Page as a member of Led Zeppelin (and in his own right as a solo artist) at the Atlantic Records 40th Anniversary concert.
