And this song

But early Genesis, that lineup in particular. When they were five, lol.

In Chicago. They were magnificent. But when they were down to 3 they sure learned how to fill the void with new full sound making their "new" sound. Then when Hackett and Collins joined they became really progressive and full.
Adding new equipment they got from King Crimson and having to use bass pedals and a fuzz board to add fullness when they were at 3 and 4 members. They developed into their own uniqueness.

Thru Wind and Wuthering, that was their last good album in my opinion.

Then Collins and Gabriel broke out on his own .
