The Prodigy have to be up there as one of the most awe-inspiring live bands.
It's not just the pulsating bass thundering around the arena, or the hypnotic dance beats blasting every atom in your body, or even the angry, aggressive lyrics that are spat out.
But it could well have something to do with the awesome frontmen of the band, Maxi Reality and Keith Flint. These are men with serious attitudes and they know how to challenge a crowd with their very presence. Maxi, a statuesque 6ft 7ins, paced across the stage with the confidence of a man who knew the legions of fans worshipped at his altar.
A white mask painted across his eyes added to the menace. It was a dramatic comparison with the maniacal Keith Flint, a scowling man who has more than a hint of danger in his wild eyes and whose in-your-face attitude is very much of the Johnny Rotten school of etiquette.
During an hour-long set and two encores of songs mainly from Their Law, a CD of singles from the past 15 years, no one dared - or wanted - to stand still as the incendiary tracks exploded in our faces.
Predictably, Firestarter and Breathe got the crowds going, but all the songs were formidable, from Charly - the '91 track that changed the face of dance music - to Spitfire ( dedicated to the memory of George Best) and Voodoo.
We'd already been primed into action by Audiobullys, London duo Simon Franks and DJ Tom Dinsdale.
It was a night no one wanted to end. When it did, it was then we realised just how much our bodies had toiled. We had nothing left to give.
