Porcupine Tree
Porcupine Tree is a British progressive rock band formed in Hemel Hempstead, Hertfordshire, England. It is the most successful project by musician Steven Wilson, as evidenced by its growing popularity. A mix of early progressive rock, psychedelia, ambient and, more recently, metal is present in their recordings. This shouldn't come as that much of a surprise given that self-taught audio engineer and producer Wilson listens to many different genres of music for inspiration. 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."
