I'll be in the minority(maybe not here, but overall), but I find that Profanatitas... is still better. Which is not to say that Disgusting... is anything but fantastic. One noticeable change is in the melodies; they're much more agile, having less of the decaying, hammering nature that was in the debut album and turning into something more like a primal expression of inner fury. It's actually a bit surreal to hear Profanatica becoming so melodically expressive. This is especially apparent towards the end of the album. Another change people will talk/have been talking about is the use of actual drums... I couldn't care less either way(I actually liked the drum machine in the debut), but you'll definitely notice a difference in the sound.
I'd be glad to upload it but I only bought it on vinyl and don't have a way of transferring that into digital files.
