01 / About

A week in Coimbra

SemRede is a week-long event in Coimbra, bringing together people who care about offgrid communications, self-sufficient living and thriving communities.

Share knowledge, learn new skills, meet like-minded people and be part of a growing movement.

"Sem rede" is Portuguese for "no network": the moment your phone loses signal. This week is about what we can still do when that happens.

living

Invited artist
Haleen

Haleen, a musical project by a Belgian couple based in off-grid Portugal, has crafted a distinctive genre inspired by their energy shift and consciousness transformation. Their music is described as mind-opening, hypnotic and uplifting, giving listeners courage and lifting their mood.

Hans started his musical journey at a young age, moving from the metal scene to an acoustic guitar tuned to 432Hz. Embracing electronic music, he blended diverse genres into a sound that crosses boundaries.

Kath had a rapid shift in musical taste, moving from mainstream hits to Electronic Dance Music, influenced by artists with a powerful energy. Her palette includes sounds from Sam Garrett, Mose, Peia, Yaima and Ajeet, mirroring her inner transformation.

They perform live, connecting with audiences through love and acceptance.
