Decibel Outdoor is the largest harder styles festival on the planet, and it has held that title by going broad rather than narrow. Founded by Dutch promoter b2s in 2002 with a single day at the Binnenmaas recreation area near Rotterdam, it moved to the Safaripark Beekse Bergen in Hilvarenbeek and grew into a three day, weekend long event. Today it spreads roughly 30 themed stages across the park, covering every corner of the hard dance map: melodic hardstyle, raw, rawstyle, hardcore, uptempo, terror, jump, hardtrance and hard techno. Recent editions pull crowds in the region of 120,000 over the weekend, plus a camping village that b2s calls the Loudest City on Earth. The mainstage is the centerpiece, where every year carries a fresh Decibel anthem and a purpose built endshow, from Rebelion's Beyond The Horizon to the Ran-D and Unresolved anthem shows. After the dust settles, b2s posts those mainstage sets free on YouTube and SoundCloud, so the archive runs deep even though the festival rarely streams live. The 2026 edition lands on 28, 29 and 30 August, with more than 300 artists already billed across the weekend.

Decibel Outdoor has only run a true concurrent livestream once, in August 2020, when the postponed festival was replaced by a free seven-hour STAY LOUD broadcast on live.b2s.nl. In normal years the festival does not stream the event live. Instead b2s records the mainstage and releases full sets for free on its official YouTube channel and SoundCloud, dripping them out over the weeks and months after the festival. That archive is deep, covering recent editions from 2017 through 2025, including anthem shows and bespoke endshows, but it is on demand rather than live. There is no paid or ticketed stream and no confirmed concurrent live broadcast for the 2026 edition.
It is the largest harder styles festival in the world, covering the full hard dance spectrum from melodic hardstyle to terror and uptempo across roughly 30 themed stages.
Each year b2s commissions a new official Decibel anthem and a custom mainstage endshow built around a single theme, with productions like Rebelion's Beyond The Horizon and the Ran-D and Unresolved anthem shows.
The festival runs three days at the Beekse Bergen safari park and adds a multi-day on-site camping village branded as the Loudest City on Earth.
It is one of the few major hard dance events that spreads its mainstage video sets across SoundCloud and YouTube for months after the weekend, keeping the full archive free to stream.
The festival takes place at Safaripark Beekse Bergen in Netherlands. It typically hosts crowds in the 120,000+ range across 3 days.
