In 2008, they released their fourth studio album, Idolum, pushing even further the monolithic sound and psychedelic vein of their music to a new level of composition.

The band's latest studio album 8 came out on 22 September 2017 through Neurot Recordings and Supernatural Cat for the vinyl release in Europe.

It is a continuous flux of music (its title symbolizing infinity), a single stream divided in 8 songs, recorded live together with no overdubs with the exception of vocals and synths.

The sound of Urlo's bass and Poia's guitar are typically distorted, Vita's drum rhythms are slow and the band uses psychedelic and hypnotic visuals during the live shows.

The sound of Ufomammut is the product of research around the instruments and amplification setup, resulting in the use of custom tube amplifiers with heavy full size cabinets, and B tuning on guitar and bass.
