Porcupine Tree

Their music is a combination of rock, psychedelia, ambient and, more recently, metal. The main songwriter and founder of the band, Steven Wilson, once commented: "I like so many different types of things, and they all go into the melting pot, if you like, that produces the music of Porcupine Tree."
