Dilate is definetly one of her best pieces of work. I find them different from other lyrics because they give me more of a deeper meaning, which touches my soul. Maynard writes the songs with poetry that flows with life. I haven't heard any lyrics which produce such a feeling. Tool's genre would fall under metal, but they have their own unique style that no one else can produce.
Tool throws in a variety of playing hard and soft music, constantly switching back and forth.
You get a bit of both in each song. Tool has musical talent that I have never really understood. Maynard's voice produces the melody very calm and clear. The guitar and bass work together to produce excellent talent while the drumming has it's own style of music. By adding these elements together you get an unpredictable style of music that will keep you listening for hours.
