An experimental Faggy Hippie Rock band which was literally created by Musician Steven Wilson who recorded his own drums, guitar, bass, vocals, and synth effects in the early 90's.

For the most part they play unique keyboard/acoustic ballads but in their recent albums have taken a more metal approach to their music. Their best CD however is of course the Metal/Synth experiment called 'Deadwing'.
Porcupine Tree? They are bad ass.....but Wilson won't tell anybody what the hell their name means.

When a girl's hair down there stratches a clean-shaven guy's face, when he eats her out, the same way a guy's stubble would ussually stratch her part.

Can also be known as an Itchy Beaver, though that also has seperate meanings.
