Father Sky Mother Earth is a drone/doom metal duo from Hamburg, Germany, featuring Nico Seel on guitar and Niclas Gerull on bass. Their albums — the self-titled debut (2016) and "Across the River of Time" (2017) — create dense, meditative drone soundscapes drawing comparisons to Sunn O))), Bongripper, and Earth, described by critics as "superior drone" with ritualistic, pounding rhythmic elements.

Fregoli Delusion is a drone/funeral doom metal project from Vilnius, Lithuania, formed in 2021 and named after the rare psychiatric condition in which the sufferer believes different people are a single person in disguise. Their output trades in the slowest, most oppressive extremes of doom metal — glacial drones and suffocating funeral doom.

FRIG is an avant-garde/drone/industrial metal project from Bucharest, Romania, formed in 2017. Their Romanian name — meaning 'cold' — matches the frigid, experimental character of their drone and industrial metal from the Romanian capital.
