Knowing Just as I is my favorite, but really..... Lots of good albums from these guys. Personally, I don't care for the newest one ("Aberrations") nearly as much, as it seemed to just really simplify the formula too much. Hoping they have a new one before PP.....
Also, make sure to avoid the s/t album like the plague. It was a spinoff band while the rest continued under the name Lefay, and it is AWFUL. The Lefay albums (SOS, Seventh Seal) are both excellent though.
And yes, I've always thought that Morgana Lefay had a lot in common with early Savatage.
