Passage or Solar Soul?

Passage

But Ceremony of Opposites is their best, and it comes just before Exodus, so you're guaranteed to like it.
 
oh DEFINITELY Passage

"Moonskin", "Born Under Saturn", and "A Man In Your Head" are among my favourite's of theirs.

but check out a few from Solar Soul, since you can after all try before you buy, legally: "Alliance", "Quasar Waves", and "Solar Soul". If you liked Lesson in Magic and Era One then you may like Solar Soul, but if you prefer the earlier stuff, yea, stick with Passage.
