Born in 2012, OTUS takes elements of post-metal/sludge bands as Isis and Cult of Luna, passing through the Black Sabbaths doom up to the experimental music of Tool, Om and Sunn O))). The band enriches their sound playing ethnic instruments, building their own synthesizers, chanting mantras and taking particular care of their visual and symbolic identity, from poster art to visual projections. After their first demo-ep released in 2013, Otus took part in several gigs and festivals playing with great bands as Intronaut, And So I Watch You From Afar, Toner Low, Scale The Summit, and Shores Of Null. About the album: "7.83Hz" is a concept album divided in 3 chapters and inspired by Timothy Leary's quote: Turn on, Tune in, Drop Out. This musical journey intends to be more empirical and scientific rather than religious/orthodox, showing a possible way to reach the "Doors of Perception", to tune in with the Universe and finally to reach a lucid detachment. The conscious "Emptiness" reached through spiritual practices such as meditation and recitation of mantra, takes shape in the 70 minutes of musical solutions contained in this record, reaching their fulcrum at the frequency of 7.83Hz also known as "Buddha's frequency".
