I'm working on my MA in Christian Studies at the University of Mobile (Alabama) and have been listening to the harder stuff in Christian music since I was like 8 and bought my first Whitecross album (yes, i'm that old!) I bought Mortification's "Scrolls of the Megalloth" on tape when I was 14 (!!) so I'm pretty much old school (seeing the 90s as the heyday for Christian hard music). I like some new school stuff (Demon Hunter, Maylene and the Sons of Disaster(saw them in concert this past monday!), Flyleaf, etc.) but a lot of the stuff out there is so generic (imho) and it seems it was just put out to make a buck.
I have pretty eclectic tastes, ranging from emo style a la Pedro the Lion to hardcore like Six Feet Deep and Spoken to the growling death metal style of Mortification, Lament, Ethereal Scourge, etc.
