metal is generally frowned upon by christians, somehow linking ALL metal to the antichrist (ok, ok, most of it is!!
). I have heard the band you speak of on the radio and it will be hard to find emotive metal of that calibre which is pro christianity. Metal listeners are generally summed up as people who have lost faith in humans as a species
The biggest market for Metal is no doubt of the angrier variety from the US, South america and Europe (Sweden and Germany in Particular)
HOWEVER! all is not lost, since i am a huge metal fan i decided to browse google for you and found this interesting link :
metalforjesus is an ORGanisation which can help you out
it might be worth checking out, and the best way to find more bands is to search for them yourselves! then they will be that much more special to you. The sound you will be after is progressive or 'new' ('nu') christian metal, and taking the percentage of christians in this world, i am sure there is a market for it!
I know nu-metal such as P.O.D and the like are christian, but don't have many more examples
Never give up hope, and i'm sure you will find pro christian metal, but i can assure you that even the most die hard metalist listening to the likes of 'Morbid Angel', 'Slayer', 'Unleashed', 'In Flames' and 'Bloodbath' like myself doesn't make us satanic!
Metal is a muscial art which has not been corrupted by the major labels or popular mainstream like most music and the quality therefore, in my opinion, is unrivaled (well, perhaps by jazz or orchestral ensembles). You cannot be a hot, long locked , leather wearing band of studs to get ahead in the metal market. Metal gurus will only appreciate bands who are musically sound artists, and the beauty is, you don't need a face like Britney Spears to get ahead, if you catch my drift
good luck and enjoy some quality music!
