The only exception being Boom 2023 which is also the first ever consecutive edition, taking place during waxing crescent moon and with the theme "Radical Love".

Born in 1997 in Herdade do Zambujal, Águas de Moura, Portugal as a goa trance psychedelic party, it has since then evolved into a global celebration of alternative culture.

Boom's Environmental Paradigm has gained a reputation for its hand-on, fusionist, experimental approach for large scale gatherings.

It is based on the following dimensions: art and creativity; water; air; soil; waste as a resource; public health; food and nutrition; engagement and social change; energy, mobility and transport; packaging; procurement and materials.

The 13th edition of Boom Festival took place on 22–29 July 2022 with The Anthropocene as its main theme, after being rescheduled due to the COVID-19 pandemic.

They introduced the psychedelic movement in Portugal in the early 1990s, with regular parties in a forest and in 1997 decided to organise a festival which would bring together the Goa trancers from across the world.

Between 2002 and 2008, the festival started to develop not only a multidisciplinary vision of the psychedelic trance culture and beyond, but it also pioneered multiple sustainability and regeneration projects.

Psychedelic means mind manifesting but has been associated as an attribute for music, arts in general and alternative ways of life.
