Drummer Ray Hearne says: "Darkest Light is based on Blind, one of our favourite tracks from the original demo. We've managed to chop the old song in half, cut away all the excess fat and produce a six-minute rowdy riff roller-coaster that will find a home in the heavier side of our live show."

Restoration follows Haken's third album The Mountain, which earned the group three nominations at this year's Progressive Music Awards. The band tour the UK next month as part of a Prog-sponsored bill also featuring Leprous and Maschine.
