LED ZEPPELIN

Led Zeppelin's first album is a good hard rocking blues album. There is some psychedelia thrown in, and maybe, just maybe a dash of prog. There is some inventiveness to Dazed And Confused and Communication Breakdown, and a bit of psychedelic sounding keyboards in Your Time Is Gonna Come, and even some Eastern influence folk in Black Mountain Side. But if that's all it took to be prog, Aerosmith would be listed here.

Needless to say, Led Zeppelin's later albums, especially their fourth, had enough experimentation and adventurous compositions to warrant their inclusion. But this album, as it is, a great blues rock album, can only rate three stars from me.
