End of the sixties the british scene was all about blues. Alexis Korner, John Mayall were the people helping young and talented guitar players start their career, like Peter Green and Eric Clapton. Jimmy Plant, guitar player of the Yardbirds, belongs to this generation of blues gitarists, that changed from traditional blues to the exciting music of the seventies with hard powerful rock music.
The first album of Led Zeppelin, around 1969, has a blues background, but the guitar, the bass and drums are loud! Combined with the somtimes scary voice of Robert Plant this started a new genre. Dazed and Confuzed is the end of an era and the start of a new. The second album, with Whole Lotta Love, was a real hard rock album and Jimmy Page and Robert Plant had created a new kind of music: hard rock.
The band performed for a long time, made many albums but like many good bands it stopped in the eighties. Jimmy Page continues to play, often with Robert Plant doing the vocals.
For me Jimmy Page is a guitar player who always adds something perfect to his often simple looking playing. See here for a good bio of this band.
