Echoes and Signals, created by Russian songwriter, guitarist, vocalist, and producer Fedor Kivokurtsev, embodies the "unity of opposites" philosophy. Launched in 2012 as an instrumental project blending progressive rock and post/math rock, its journey began.

The debut EPs Comma and Ouroboros (with Vladimir Pozdyshev on drums and Alexey Zaytsev on bass) paved the way for the vocal-infused V (2014, with Yaroslav Egorov on drums). Monodrama (2017, with Egorov and Zaytsev) featured Mariana Semkina on "Lead Astray," alongside tours with Pain of Salvation and others.

In 2021, the project embarked on an evolving cycle with Mercurial (featuring Leo Margarit on drums and Alexey Zaytsev on bass), a collaboration with producer Alexander Perfilyev. Inspired by alchemy, it explores psychological transformation through vocal-driven tracks. The journey deepened with Lunar (2023, with Alexander Kulkov on drums), examining the moon’s duality—its power to inspire, mislead, and illuminate hidden paths—guided by the phrase "Keep your eyes wide open, keep your mind wide shut." The cycle expands further with the EP Between Mars and Venus, positioning Earth between celestial archetypes. It dives into myths of a fractured wholeness, framing separation as consciousness itself—the act of carving meaning from chaos—and reflects the alchemical "great work" of refining the boundless prima materia into something transcendent, with more chapters yet to unfold. Musically, this cycle draws from classic prog rock bands of the ’70s and the electronic ambience of Vangelis, blending vintage textures with modern intensity.
