No. 2: Led Zeppelin, ‘Led Zeppelin’ – Best Debut Hard Rock Albums

Dating back to the late '60s, Led Zeppelin may have been the band that truly launched the hard rock genre. In a period where the British Invasion and psychedelia ruled, Zeppelin dug deep into the blues, turned up their amps and delivered a power that seemed unrivaled at the time.

Their self-titled 1969 debut gave music fans such classics as 'Good Times, Bad Times,' 'Babe, I'm Gonna Leave You,' 'Dazed and Confused' and 'Communication Breakdown' -- tracks that showcased Robert Plant's incredible range and soulfulness, as well as Jimmy Page's standout guitar playing and one of the baddest rhythm sections in rock -- bassist John Paul Jones and drummer John Bonham.
