Algae Dust began as Al Setili's first solo project and has since evolved into a collaborative trio. Setili is joined by Gram Tolish on drums - the two reuniting a few years after playing together in their former band, Frankie Valet - and Hannah Rainey of Shady Bug on guitar/ bass. Hannah's addition to the band also marks a musical reunion as Rainey's own solo project, Hennen, released a split record with Algae Dust in 2021.

In Hindsight blends the ethereal underpinnings of Algae Dust's debut release with full-band elements of rock guitar, shoegaze fuzz, and indie pop melody.
