Enigma is the third album by British progressive metal group Aeon Zen. Reviews were generally positive, with AltSounds calling the musicianship "stunning". The album made some departures from the band's previous sounds, with Fireworks magazine noting that "Divinity and Eternal Snow have bursts of growly vocals on the heavier parts", but in spite of this, Prog still deemed there to be an "overwhelming sense of cohesion on this record". Metal Hammer seconded this opinion noting the way that "those theoretically disparate stylistic stands combine to create something that thrums with vitality and a laudable devotion to making music that impresses and resonates".
