Porcupine Tree is unquestionably one of the most difficult-to-categorize and innovative bands working today. The music is breathtaking, ranging from psychedelic trip-hop to progressive metal, and a compendium of other sounds and genres in between.

The band is fronted by Steven Wilson, who is well-known for his work producing other artists, from Swedish progressive death metal group Opeth, to Norwegian chanteuse Anja Garbarek. He also has several other projects, including No-Man, Bass Communion, and the highly acclaimed collaboration with Israeli musician Aviv Geffen, Blackfield.
