I love NIGHTMARE from France but their 80s albums(WAITING FOR THE TWILIGHT from 84 and POWER FROM THE UNIVERSE from 85. Then in 99 they released a good ep with some cool songs named ASTRAL DELIVERANCE and then LIVE DELIVERANCE in 2000, live with many old songs. After that i lost interest in the group because they started to sound different.
GRAVEWORM is a false black metal band from Italy, DARK MOOR are one of the worse bands from Spain (check out AZRAEL or SARATOGA, they are so much better). HEIMDALL debut album was not bad but i think that many other italian bands of the late 90s were much better like SHADOWS OF STEEL, DRAKKAR, SKYLARK, MEZMERIZE etc....
BAL SAGOTH is one of the favorite bands of the singer of SACRED STEEL but i never carred about them. About the rest, ni fu ni fa.
