Tool are an American group of performers of popular music (though the complexity and intellectual nature of their work belies the term) whose music includes elements of heavy metal and [art rock]?. Their music features dark, complex harmonic structures, unconventional time signatures, and the angered voice of singer Maynard Keenan. |
