I learned a part for "Lucifer" to-day, and while it's not listed among the instruments in the credits on the Alan Parsons Project's website, I think it's kantele. It first appears at ~1:42 and is repeated at ~3:02. I was writing out the notation as I learned the part, and it reminded me of the kantele part in "I Robot," so I found my notation for that and compared the two.
Here's what I think is a kantele in "Lucifer":
And here's the kantele part in "I Robot" (starting ~4:26):
There's a bit of similarity in the melodies, but only in that there are a fair number of conjunct note groups (more in "Lucifer" than in "I Robot"). The main similarity is rhythm. In both, almost every other measure consists of a whole note that's tied to a note in the following measure.
Of course, both "Lucifer" and "I Robot" are also instrumental tracks that start their respective albums, so this might be an intentional resemblance.
