Vechigen are a Swiss based group specializing in the ambient, downtempo, chill out genres. "What We Don't Know" is their debut on Elemental and an impressive one at that.The title track gives us an epic movie score vibe, huge big sweeping pads filled with beautiful melodies conjure up a perfectly balanced universe. Superb beats add effect to this and you soon find yourself locked in for the duration."We Don't Change" comes in two versions, the original and vocal mixes. Pure synthesized bliss pours out of the speakers, deeper vibe here with the pads and bass, beautiful voice synths raise the euphoria levels and on the vocal mix we get a spoken vocal that works so well, super chilled vibes all round.
