As with the definition of Evo, Skerryvore - named after a remote reef in western Scotland - have stealthily evolved their driving Celt-rock sound over the past 12 years.

Opening at full throttle with that big emphatic sound of thundering drums and pipes, as rich as a Scottish single malt, it lays down the gauntlet for this captivating album that for 45 minutes draws you into another world that is vibrant and emotive in equal measure.
