Let It Roll (LIR) is renowned worldwide as number one festival of drum & bass. The main edition takes place over four days, usually in early August, somewhere near Prague (venue differs). LIR features over 300 leading producers in D&B on 9 stages and is attended by over 23,000 festival-goers daily. Last lineups featured Andy C, Chase & Status, High Contrast, Camo & Krooked, Wilkinson, Netsky, DJ Hype, Noisia, Pendulum, Fred V & Grafix, Dirtyphonics, Levela, London Elektricity, and many others.
Winter edition is held over two days in late February in Prague and is equally popular. True lovers of drum & bass are offered to buy Combo tickets which give access to both summer and winter editions. Moreover, growing popularity led to LIR on Tour which occurs in mid-spring in Ostrava, the Czech Republic's third largest city.
The history of LIR dates back to 2002—the first Let It Roll took place in one of the Prague's clubs. It remained an indoor event until 2008, the breakthrough year of the initial Let It Roll Open Air.
