Try Wonder What's Next album by Chevelle, Flyleaf, Hurt Vol. 1 and 2, older stuff by Breaking Benjamin, Bush, Crossfade, 10 Years, Evans Blue, Three Days Grace, Helmet. Might not be brutal enough for you but most of it is pretty hard rock, some songs might be a nice change of pace for you. Anyway those are some of my favorites. Hurt is really good if you are into classical influenced stuff, their music is very sound theory-wise and it might surprise you.
