"Existência" - new single extracted from the solo Ep of Rodney Marcellus (vocalist/bassist and multi-instrumentalist of the band Low Embryonic Cells) shows his evolution singing in Portuguese his native language and playing all the instruments and producing together with his great friend, Marcos Nagasaki. This single shows a more emblematic sound, dark in arrangements deep in personal issues, in its lyrics. It explores electronic elements with sporadic use with electronic drums and well arranged, bass lines maintaining the essence of post punk, abusing samples and atmospheric synthesizers, guitars following the same atmospheric line with the use of various effects, and the melancholy voice of Rodney Marcellus.
