Nailbomb absolutely rock!
I used to have a bag with their logo painted on it. But I stopped using it around 1998, as a couple of nailbombs went off in London, and I thought it'd be in poor taste.
It's Max Cavalera and Alex Newport from Fudge Tunnel, with some parts played by Igor Cavalera and Andreas Kisser.
They also released a live album - "Proud to commit commercial suicide"
