According to the Roskilde Festival Website:
Introvert art-rock with metal tendencies
In a hall of mirrors you do not know where the others are – as is the case with Tool. It has been five years since the album Lateralus, presenting introvert art-rock with metal tendencies. In 2006, a new album is coming, and Tool makes its second appearance at Roskilde. The journey into Tool’s tunnelling compositions is fascinating. The listener is often whirling in distant, haunting universes, lead by Maynard Keenan’s both aggressive and emotional voice. The insisting music is accompanied by gruesome film sequences making the symbiosis of sensual impressions hit hard. A large-scale experience.
