The first time I heard them I managed to somehow overlook them
it wasn't until a friend had me give them a second go with the song "When Gjallarhorn Will Sound" that I thought they were pretty good... and then hearing The Fireblade, I fell in love.
First one i bought, was a bit hard to track down but it is a great album. i like to get a bands first album then progress with their second, third etc. simply because if i buy a bands latest album and really dig it i may not like some of their original work as much because their style has changed(which is not always bad)
