Robert Anthony Plant, CBE, is an English singer, songwriter, and musician, best known as the lead singer and lyricist of the rock band Led Zeppelin. A powerful and wide vocal range (particularly evident in his high-pitched vocals) has given him a successful solo career spanning over 30 years. Plant is regarded as one of the greatest singers in the history of rock and roll; he has influenced fellow rock singer-songwriters such as Freddie Mercury, Axl Rose and Chris Cornell. 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 2008, Rolling Stone editors ranked him number 15 on their list of the 100 best singers of all time. In 2011, Rolling Stone readers ranked Plant the greatest of all lead singers.
