In The Garden (the debut album from 1981) is a great discovery. Almost got a post-punk feeling on some songs. Great early 80s keyboard sounds and also a bass guitar in every song. Could never get enough of early 80s stuff. Annie's voice is more ethereal on this album and I really like her hair on the album cover.
They also created some amazing non-pop stuff include the under-rated 1984 goth album. Some of their lesser-known work is their best. But one cannot escape Sweet Dreams, perhaps the best pop/dance song of all time?
