X-Massacre is a hardcore and bass music festival in the Czech Republic capital Prague. This high energy party has become one of the city's favourite ways to celebrate the run-up to Christmas.
Spread across three stages, over 5,000 people embark on a fourteen hour journey through bass music, accompanied by a top of the range sound system as well as infectious visuals and production.
The last edition featured The Sickest Squad, The Speedfreak and Le Bask, who came together for a night that showed exactly why Prague is called the BPM capital of Europe.
Výstaviště Praha Holešovice is a huge exhibition centre to the north of Prague city centre.
