- Alcest began as a raw black metal project in France but has since evolved their sound to a melodic dream pop/shoegaze style inspired by bands like Slowdive and Ride.
- This change in sound divided fans, with some preferring the earlier black metal works and others embracing the new direction. However, it also attracted new fans, especially women, uncommon in the male-dominated metal scene.
- While opinions varied, many fans saw the album "Le Voyages de l'Âme" as Alcest's magnum opus, perfectly blending soft and hard elements. However, the album "Shelter" received mixed feedback for its calmer approach.
