The Butterfly Effect - A kickass Australian band that sounds like a mix of the best bits of Perfect Circle mixed with Deftones, a little bit of Tool and some strong Alice In Chains style harmonies. I highly recommend their debut album
Begins Here to anyone interested in some great modern heavy rock
Audioslave (can you still call them a new band?) are pretty damn great too.
I wrote up a review of their new album
Out Of Exile in this thread here:
