Polygon Live LDN from May 2 to 4, 2025, in Crystal Palace Park features nearly four times the usual number of speakers, with different parts of the music coming from different parts of the stage in 360 degrees.
Top DJs will make the most of this special soundsystem, including legend Jon Hopkins and composer Cosmo Sheldrake, with a mixture of genres.
In alphabetical order, Acid Pauli, ANONM, Âme DJ, Kiasmos (UK exclusive), nimino and Red Axes will now perform in 360-degree spatial audio, powered by L-Acoustics.
Acid Pauli will bring his combination of psychedelic, adventurous and musical techno to the Polygon stage. 
ANONM’s set meanwhile is defined by his complex style and unorthodox mixing, while Kiasmos duo Ólafur Arnalds and Janus Rasmussen will perform their only UK 2025 show.
They bring ethereal, minimalist piano melodies and soul-penetrating beats.
This festival is as much about the sound system as about what is playing through it – both combining to enhance one another.
A spokesperson said: “If you’re passionate about music, about sound, and about having a first-of-its-kind experience that will blow your mind, Polygon Live LDN is for you.”
“For several years, we’ve been fine-tuning a proprietary design to make our spatial audio events possible,” said Polygon CEO Nico Elliott.
“The structure we’ve settled on prioritises a movement and fidelity in the music that truly has to be heard to be believed.”
The stage design involves a huge hemispherical dome, 25m in diameter and 9m high, and rigged with almost 100 state-of-the-art L-Acoustics speakers that fully encircle the audience.
Polygon’s sound engineers then ‘spatialise’ the artists’ music around, above and through the audience.
Throughout the sound, synchronised lighting is added to this enormous structure, and you have a fully immersive audiovisual experience.
Happening in May, it will be covered in case of wet weather.
Polygon, the London-based production company putting on the Crystal Palace festival, has previously hosted festivals internationally.
