The festival has had various musical phases over the years, but since the current two-site format was adopted in 1999, rock, alternative, indie, punk, and metal have been the main genres featured in the line-up.More recently hip hop has comprised an increasing proportion of the lineup, including headline sets by artists such as Kendrick Lamar, Travis Scott, Eminem and Post Malone.The line-up for the first two years was made up exclusively of jazz performers, but in 1963, several rhythm & blues acts were added to the bill, including the Rolling Stones, Georgie Fame, and Long John Baldry, and by 1965, such acts were in the majority, with jazz sessions reduced to Saturday and Sunday afternoons only.The proposed line-up was published in Soundcheck free music paper issue 12 as: Friday 24 August – Hawkwind, Boomtown Rats, Snowy White, the Playn Jayn, Dumpy's Rusty Nuts, Wildfire, Chelsea Eloy, Tracy Lamb, New Torpedoes; Saturday 25 – Jethro Tull, Hanoi Rocks, Steve Hackett, Club Karlsson, Nazareth, Twelfth Night, Thor, Silent Running, New Model Army, IQ, the Roaring Boys, She; Sunday 26 – Marillion, Grand Slam, the Bluebells, Helix, Clannad, the Opposition, the Enid, Young Blood, Scorched Earth, and Terraplane).After Labour regained control of the council in 1986, permission was given for fields adjacent to the original festival site to be used, and a line-up was put together at short notice.1988 saw an attempt to take the festival in a mainstream commercial pop direction,[13] featuring acts including Starship, Squeeze, Hothouse Flowers, Bonnie Tyler and Meat Loaf (who was bottled off stage),[14] and the subsequent disputes led to the ousting of original festival promoter Harold Pendleton by the Mean Fiddler Music Group organisation.Attendances continued to fall between 1989 and 1991, but began to recover from 1992, when new organisers took over from the Mean Fiddler group, broadening the festival's musical policy.Singer Kurt Cobain came onstage in a wheelchair pushed by music journalist Everett True and wearing a medical gown, parodying speculations about his mental health.[16] The 1992 festival was hit by extreme weather, with a thunderstorm on the Saturday drenching the site, leaving it ankle-deep in mud, and blowing away the Comedy Tent.[24] Flags and banners had been a traditional part of the Reading Festival since the early 1970s, originally used to enable motorcycle groups and others to identify themselves and find each other inside the main arena.[30] The festivals were due to host Rage Against the Machine's first UK show in 10 years, along with Stormzy and Liam Gallagher's first appearances as headliners.
