Lightning in a Twilight Hour is the continuation of the bitterly sad, musically precise work of Bobby Wratten, late of the Field Mice, Trembling Blue Stars, and more. Working with a lineup consisting of key members of these bands, the sound of the group is slightly more electronic, a little more ambient. Early releases lean more in the direction of the indie electro of Trembling Blue Stars, though their first album, 2015's Fragments of a Former Moon, did make time for sparse, ambient instrumentals. Future releases leaned toward shoegaze and experimental soundscapes, and 2022's Overwintering added pastoral folk, indie rock guitar jangle, and clipped melodies to the mix. As with previous bands, Wratten and co. hold fast to a core of sadness and gloom while surrounding it with slowly shifting sounds that bring those feelings fully to life.
