“Forbidden Frequency” is a cosmic ceremonial journey that blends tribal trance, ancient rhythms, and deep industrial energy. Each track acts as a ritual, opening portals, shifting states, and pushing the listener beyond the ordinary human threshold. Created for psychedelic movement, ecstatic dance, and transformative inner work, this album invites you into a space where the physical dissolves, the spirit awakens, and the music becomes a force of its own.

The Ancestral Engine

Leeuwenstein is the musical identity of Alex van Leeuwen, producer, songwriter, where he transforms inner journeys into immersive, ritualistic, and psychedelic soundscapes, a Dutch artist and ceremony guide who healed from PTSD through plant medicine. His music is crafted as a sacred space: a blend of shamanic tradition and electronic innovation, with tribal percussion, ambient textures, and angelic female vocals.

Leeuwenstein’s live performances and sound journeys are deeply immersive, supporting inner healing, movement, and expanded states of consciousness. Perfect for psychedelic ceremonies, truffle experiences, and conscious festivals, his albums, such as Frozen in Time, Rhythms of the Cosmos, and The Green Path, are widely used as tools for transformation.

Leeuwenstein invites his audience not just to listen, but to feel, remember, and return home to themselves.

Though rooted in healing music, Leeuwenstein occasionally ventures into political territory, crafting powerful protest songs that reflect on war, freedom, and the future of humanity.
