Definetally DOMINE and their first album "Champion Eternal", greatly influenced by Manowar, Omen, Manilla Road and some Queen (yes). The lyrics are mostly influenced by the Elric saga. It's a classic, seriously, one of the top 3 italian metal albums for me. Their second album is very very very good too, and the rest are just good (but maybe Doomcifer will like them more than i did).
Also, of course VIRGIN STEELE, their older and classic albums (especially "Guardians Of The Flame" and "Noble Savage"), talk about battles, war, etc, but they are not as "barbaric" as Doomcifer wants, cause their influences are bands like Rainbow, Queen and although they remind Manowar sometimes, they are not really influenced by them. Also they might have 4-5 EPIC songs per album, but there will be another 3 about how good David Defeis is in bed. I like ALL their albums (except "Life Among The Ruins") and the ones i mentioned before i highly recommended, also "Marriages Of Heaven And Hell" (part 1 and 2, but 2 is better) and the first "House Of Atreus" album, which is 100% epic, but the band has like.. at least 5 albums better than this one. Jack Starr (the band's original guitar player, and main composer of "Guardians Of The Flame) created BURNING STAR, who have released a series of killer albums, the best being "No Turning Back" , not many songs about battle, but the overall feeling is of battle-ish pure u.s. power metal .
Jag Panzer also dont have many songs about battles but "AMPLE DESTRUCTION" has this feeling too. It's like they are marching to war, seriously and they are epic enough. Also this album is probably the best american heavy metal album (Manowar excluded), so its essential any way.
CAULDRON BORN, is (was?, i've lost their traces some years ago, and i think they are no more) another pure war/epic metal band, but the thing about them is that they are more technical than your usual epic band, they have lots of influences from Helstar, or even Watchtower for example, but they are not "Wanky" or anything.. they just have a huge collection of killer riff-age in their songs, all epic, all atmospheric. "Born Of The Cauldron" is their best, but their more epic is their second album, "And Rome Shall Fall".
That's it (for now)
