Led Zeppelin Houses of the Holy

What would hard rock be without Led Zeppelin? A very boring place probably... The British quartet ruled the music scene of the seventies, becoming more ambitious and tackling more and more diverse styles with each new release, from their 1969 debut to 1979's In Through The Out Door. Jimmy Page's riffs and solos inspired millions to pick up a guitar, and are still played in concert halls and music stores worldwide.
