Billed as Skelton's most ambitious composition to date, Towards a Frontier is a 66-minute epic that is part of larger multimedia project assembled during three trips to rural East Iceland. Characteristically, this is an album very much shaped by the natural environment that Skelton was immersed in as this piece was gradually conjured into being. More specifically, Towards a Frontier draws its primary inspiration from the changing seasons as experienced from an Icelandic mountain range. While less instantly gratifying than some of Skelton's other recent works, this album has a masterfully paced slow-burning majesty and mesmerizing elemental power that gradually reveals itself with repeated, attentive listens. Notably, nature does not seem particularly benign here, but Skelton keeps the mood intriguingly ambiguous as the piece unfolds, hinting at the primal, cosmic horror of our insignificance while simultaneously evoking something akin to religious ecstasy.
