I've been away for a while. Sorry.
However, my inspiration has been given a kick in the pants after coming across the Ankara, Turkey band Kasatura.
If their 2011 promo song Helmet 451 is of any indication, I would have to say THIS is where Sepultura should have gone after the Chaos AD album.
With the hooks Kasatura writes, these guys could be huge.
Check it out.
Look them up here and here.
