1997's Crossing the Rubicon was the debut album from Swedish melodic death metal band Armageddon, which was a side project of Arch Enemy guitarist Christopher Amott.
Armageddon's sound - at least on this album - is very similar to the early, pre-Angela Grossow Arch Enemy albums. The sci-fi/space-oriented lyrics also bring to mind Jester Race-era In Flames. This is very thrashy death metal with plenty of melody and precision guitar work from Amott, who is one of the best in the business. Some of these solos would be perfect on a power metal album. The growled vocals are better than average as well. My only real complaint is that the album is a bit too short, and sacrifices 11 of the 38 total minutes to a series of instrumentals and oddball experimental tracks like "Children of the New Sun". The instrumentals are interesting enough, but I'd rather have more "full" songs.
Armageddon's debut is a bit uneven, but remains a good example of what made the Swedish death metal scene in the late 90's so vibrant and compelling. If you're a fan of older (hell, newer too) Arch Enemy, In Flames and At the Gates, you should definitely try and track down a copy of Crossing the Rubicon. It won't be cheap though, and it won't be easy.
NOTE: If you decide to track down a copy of Crossing the Rubicon, you might as well try for the Japanese import version, which features a blistering cover of Iron Maiden's "Die with Your Boots On" as a bonus track.
