Tool is an American progressive rock band from Los Angeles, California known for their very long and complex albums and distinctive style.
They are Damien's favorite band, in spite of the fact that they take roughly a decade to put an album out.
Over the years, they have also become a very polarizing band, irrationally hated by ignorant people that will often declare they have "no talent", despite having the world's greatest living drummer^ and male vocalist in their group.
Their discography was covered in the first six episodes of Dropped D.
They were besmirched once. It will never happen again.
^James recognizes Danny Carey's immense talent, but disagrees and says Neil Peart is the best ever--living or dead.
