Unquestionably one of the all-time most influential, important, and versatile guitarists and songwriters in rock history is Jimmy Page. Just about every rock guitarist from the late '60s/early '70s to the present day has been influenced by Page's work with Led Zeppelin -- his monolithic riffs served as a blueprint for what would eventually become heavy metal, yet he refused to be pigeonholed to any single musical style (touching upon folk, country, funk, blues, and other genres). Page also lent a hand in writing (or co-writing) Zeppelin's vast array of classic songs and produced all their albums. at age 13 after being inspired by the Elvis Presley tune "Baby Let's Play House," and while he took several lessons, was mostly self-taught.
