I know the deal ghosthouse,
The first CD I got by  Spock's beard was "Day for Night". I listen to it once or twice and it did not grab me so it's sat on the Shelf.
Then I saw them in concert warming up for Dream Theater and it clicked!
I have loved them ever since.
They have at least 10 and a few live ones. They are all pretty solid.
Just take your time and listen to a variety of their stuff. Don't make a snap decision😎
