Not sure who you are talking to, but that album flopped, and Nicks and Buckingham were debating what to do next... you are welcome to go read both of their comments over the years on this.
I am not debating Buckingham and Nicks talent, I am stating that FM would not have become what it did without them.
It may have flopped nationally, but where I was at the time it was pretty good. It was played on the FM stations in Florida, and that’s where I first heard it. It’s raw and not well mixed, by today’s standards, but you can hear the beginnings of what would later became the Fleetwood Mac ‘sound’..................
