The Angel is an absolutely mandatory metal release.
It's really the 'beautiful' side of MDB. All clean vocals, many tremendous violin solos, etc....and just a great atmosphere.
The tracks "From Darkest Skies", "Cry of Mankind" and "Black Voyage" are eerie, depressing and glorious all at the same time. I'd recommend the digipack as it was remastered.
As I see, MDB has never released a bad album, although some are obviously much stronger than others.
If you only have "Words", I'd recommend that you immediately pick up:
Angel
Turn Loose the Swans (arguably the best metal album ever)
