Rage Against The Machine are headlining this weekend's T in the Park in Scotland, 15 years after playing the first ever music event.
In 1994, the LA punk/rap band appeared alongside Primal Scream, Oasis and Manic Street Preachers at Strathclyde Park near Glasgow, the original location of the festival.
But 11 years ago, it moved to the bigger site of Balado near Kinross.
So far, around 10,000 people are estimated to have set up camp with the remaining 70,000 expected on Friday and Saturday.
Rage are back
Led by charismatic frontman Zack de la Rocha, Rage were one of the most highly politicised bands in recent memory.
Seeing themselves as modern revolutionaries, they constantly criticised the US Government's policies at home and abroad.
But they are also one of the most exciting live bands in the world.
The band split up eight years ago, eight years after their self-titled debut album was released.
One of the biggest hits from it was the now legendary Killing In The Name of, which is almost certain to be on their set list.
Following their split, members Tom Morello, Tim Commerford and Brad Wilks went on to form Audioslave with former Soundgarden singer Chris Cornell.
They played the main stage at T in 2005 but split this year.
Since then, they've played several festivals in the US.
This weekend is the first time that 25-year-old Mark from Ardrossan in Ayrshire will see them.
He said: "I know they played 15 years ago but I was a bit young to go.
"But I'm looking forward to seeing them on Saturday."
The weekend will also see a set from Amy Winehouse on Sunday.
It will be her first UK show since her now infamous appearance at Glastonbury, when she ended up punching someone in the audience.
Online bookies have odds of her not turning up for the event running at 3/1.
Other bands appearing include Kings Of Leon and The Fratellis
Among the headliners which also include Chemical Brothers and REM, there are a lot of new Scottish bands vying for attention for the music press.
Isoceles, Frightened Rabbit and Sergeant are all being tipped for big things this year.
Glasvegas were one of the most hyped bands at Glastonbury and return home to play the Futures Tent on Saturday.
Singer James Allen admitted he isn't feeling too over-awed by the occasion.
He said: "I'd be lying if I said I was looking forward to any gig but when I'm there and I've got my guitar on, it's the best feeling in the world.
"Playing rock and roll music."
As with any UK summer festival, the weather will play a big part this weekend.
Friday is due to be pretty bad with heavy showers expected.
But Saturday and Sunday should bring some sunnier skies.
At around £180 a pop, T in the Park is apparently the most expensive festival in the UK but sold out in just over an hour.
Nineteen-year-old Matt from Portsmouth has made the long trip north for the event.
He said: "It was such a brilliant weekend last year, so I've come up here rather than Glastonbury.
"The line-up isn't as good as last year but it was still worth it."
And 21-year-old Kirsty from Ellie in Fife's reason was simply a matter of the location.
She said: "This is my fourth year here. It's just the closest festival."
