House music originated in 1980s Chicago, pioneered by Frankie Knuckles at clubs like "The Warehouse". It featured repetitive 4/4 beats and synthesized basslines. In the late 1980s, house music gained popularity globally and was infused with mainstream pop in the early 1990s. The UK developed chill house in the 1990s. Illegal raves featuring house music were also common in the UK during this period. From 2000-2010, vocals became more prominent in house music and festivals dedicated to the genre emerged. From 2010 onward, progressive house rose in popularity through artists like Swedish House Mafia. However, few prominent female DJs have achieved the same global success as their male counterparts in the house music genre
