Emerson Lake and Palmer

Obviously, these are also 11 of the best progressive rock songs ever!

These songs might go for 10, 20 or even 40+ minutes!

These records barely retain their creators’ “prog” trademarks.

They play to the beat of their own drum.

A thoughtful way to pay tribute to the band's legacy.

Can you believe there are this many?

They experimented with the mainstream.

Rockin' a full half century.

Demons, gravestones, blood and motorcycles on an album cover often mean you're about to hear some metal. But not always.

This was both the boldest move the band ever made, and the beginning of their undoing.
