I didn't listen to the album so what kinds of "different things" are you talking about?
Because if you think these guys or A7X are leading the pack of bands "trying different things" in metal then I just don't know what to really say.
As far as 5 Finger goes, there is a little bit of humor in the music, whereas I feel like most bands in this genre take themselves too seriously. All of it sounds the same to me, and I feel The Way of the Fist is varied in style. They will only get better in my opinion, but that will probably mean leaving the metal scene all together.
A7X used to be pretty much inaudible screaming and sloppy playing ( can't stand either ), on CIty of Evil he changed his voice alot and the band became more alternative metal ( more my style ), and on the newere one, experimenting with all types of instruments. There is a broadway/opera styled song, 2 "country" type ballads, talk box, children's choir, female vocals, etc.
Not saying it's the best shit in the world, but it fits MY taste fine, and I'm all for proggression in musicians, fuck sticking to one style unless your name is AC/DC lol.
