Going to Reading or Leeds festival this weekend? Here's 30 acts you should try and see starting with Green Day. After an unbelievably well-attended NME stage secret set last year - they actually had to cordon off the stage - the Cali punks are back this year to headline the main stage, with plenty of room for everyone. Don't miss out.
Providing he recovers from his current back problem, Frank and his Sleeping Souls are to play their biggest Reading and Leeds shows yet, continuing a deserved rise up the stages from their beginnings in the Lock Up. It's sure to be a highlight.
After pulling out of his headline performances in 2000 due to not being let into the UK, it's all the more important you catch one of the most iconic rappers in the world at this year's event.
After blistering sets at Glastonbury and T In The Park already this summer, and on the back of their third album 'Holy Fire', Foals are ready to make their main stage debut at the festivals to draw their summer to a close. Expect a huge crowd.
After all of Odd Future laid waste to the main stage at Reading and Leeds last year, Tyler The Creator and Earl Sweatshirt's double-act, named Earlwolf, are back this year for more guaranteed chaos.
Biffy Clyro are Reading and Leeds veterans, and few could deny they deserve this headline slot. Expect a career-spanning set, encompassing everything that's brought them to headlining this major festival.
Nine Inch Nails
Arguably capable of headlining the festivals themselves, Nine Inch Nails play right before Biffy Clyro, meaning the main stage is probably the only place to end your Reading festival on the Sunday night, with a huge rock double-header.
If you like your music made on macs rather than with guitars, then Skrillex is a more than apt alternative for Green Day, headlining the NME/Radio 1 Stage.
Preceding Skrillex on that stage on the Friday of Reading, A$AP is touring his second album 'Long. Live. A$AP' and it's sure to go off in a crammed tent.
Since Bastille were announced to play the NME/Radio 1 stage at this year's festival, their popularity has exploded. Good luck trying to actually get inside the tent.
Continuing a gigantic summer of festivals in support of 'In Love', Peace take to the NME/Radio 1 stage. Don't bet against main stage next year.
Touring in support of their debut record 'Sistrionix', Deap Vally are getting stronger and stronger with every performance, and this is looking to be their best yet.
Headlining the tent at the same time Eminem is on the main stage, Alt-J is the perfect choice for those who like their evenings to end a little calmer. 'An Awesome Wave' still sounds, erm, awesome.
Main Stage Reading and Leeds is a massive deal for Jake Bugg, but as his Pyramid Stage show at Glastonbury proved, he's more than up to the challenge.
Arguably unlucky to be playing the tent rather than the main stage at the festivals, Tame Impala's sets will be intimate, rammed and brilliant.
Catching a few Smiths classics as well as tracks from Johnny Marr's recent album 'The Messenger' in the intimate surroundings of the NME/Radio 1 tent is a must.
With the brilliant debut album from Palma Violets, '180', still ringing in everyone's ears, they're also playing the NME/Radio 1 stage.
Fresh from R Kelly collaborations, French stars Phoenix are headlining the NME/Radio 1 stage on the Sunday night of Reading, if you want to end your weekend on a poppy note.
We still haven't had a debut album from Azaelia Banks, but the brilliance of her live show can't be denied, and she brings it to the NME/Radio 1 stage on the final night of this year's Reading.
Disclosure haven't had a weekend off this summer, touring number 1 album 'Settle', and you wouldn't bet against a few guests appearing with them at these shows.
With debut album details finally with us, R&L is a great chance to preview the tracks that are to appear on HAIM's record 'Days Are Gone'.
Jagwar Ma take to one of Reading and Leeds' new stages for 2013, the Radio 1 Dance Stage, and are sure to christen it in style.
American producer Baauer has a lot more in his arsenal than just the 'Harlem Shake', and he'll be hitting the Dance Stage on the Sunday of Reading this year.

Currently working on his first studio album, American rapper Action Bronson is the hottest of prospects, and plays on the festival's other new-for-2013 stage, the BBC 1Xtra Stage.
Chance The Rapper
Reading and Leeds are notorious for being breeding grounds for future megastars, and it's not hard to imagine Chance The Rapper being added to this list. Not one to miss.
After recently telling NME her new album is "definitely not hip-hop", it's worth going to check out Angel Haze's sets to see whether this comment rings true in any new material the rapper premieres.
