Friendship's vile, antagonistic, blackened, sludge-tone hardcore remains focused on delivering maximum auditory torture.

Considered alongside other luminaries such as Full Of Hell, Nails, and Infest, and underpinned with the oppressive tonal amplification of Sleep, Coffins, and Iron Monkey.

The band is widely considered visionary in the field of heavy modern music. Their second LP, Undercurrent showcases Friendship's hybrid of ultra-heavy doom, sludge and power violence.

With a refined technical and precise approach, and a brighter and sharper tone than the preceding Hatred LP.
