"Glass" is a standalone single released by From Her Eyes on 21 September 2015, being preceded by the band's EP Demons.
With the addition of guitarist Joe Shutt, the band wanted to introduce heavier elements to their sound indicative of deathcore and the technicality of progressive metal without abandoning their melodic roots Whilst still holding melodic elements and consistent lead lines, the tuning is dramatically lowered (from C# Standard seen on Demons to Drop A#), and is contrasted with Shutt's more visceral rhythm technique and riffs.
This is something the band states was not planned, and was an impromptu idea that ended up being included in the final mix.
However, 6 months after this release From Her Eyes amicably disbanded, shelving plans for a follow-up record.
The band released a music video of Glass on 21 September 2015, produced by Storm + Shelter.
