So, are we ready to rock?!
Sonisphere Festival kicks off today at Knebworth House and, for all you lucky readers who have secured tickets, here is a run down of what's going on.
The weekend boasts an amazing array of bands including Slipknot, Weezer, Motorhead, Sylosis and Orange Goblin, to name a few.
There are also some new editions which were announced just last week: Ginger Wildheart, Spy Catcher, Mad Dog, James Cleaver Quintet, Feed The Rhino and Witchsorrow.
However, the festival really kicks off with a bang today as metal giants the BIG 4 - Metallica, Slayer, Megadeth and Anthrax - will be taking to the Apollo Stage.
The foursome will join together in the UK for the first time in history to headline.
See the full line up below but please be aware these are subject to change.
Sonisphere organisers say they have considerately scheduled the stages to avoid painful decisions, and, of course, the Apollo and Saturn Arena stages are timed to ensure no clashes.
If you need a rest, check out the other activities on offer.

  • Slipknot fans will be able to pay their respects to the late Paul Gray, the band's bassist who died last year. 'Maggots' can leave a personal tribute in the book of remembrance at the Metal Hammer signing tent for the duration of the weekend.
  • Stop by the new pub stage in the Bohemia bar on Friday, Saturday and Sunday nights for karaoke parties.
  • The Silent Disco will also be held in the Red Bull Ten from 11pm until 2am.
  • There are also late-night DJ sets to look forward to in Bohemia, with A1 Bassline and Fold providing tonight's entertainment.
  • The cinema screens will be showing footage from last year's Sonisphere Festival. These will be shown on the Saturn screen from midnight.
