Five years ago, I lamented the lack of loudness at an AC/DC concert. 

Well, they sure amped up the volume at Etihad stadium, where 50,000 fans gathered for what could possibly be their penultimate and most deafening Australian concert ever.

Speculation is rife the boys may be winding down after the Rock Or Bust tour that has delivered a powerful mix of old tunes and more recent offerings.

The set list includes Dirty Deeds Done Dirt Cheap, High Voltage and You Shook Me All Night Long, TNT through to Sin City, Baptism of Fire and Rock or Bust ? the opening song (yes, there were fireworks).

Lead singer Brian Johnson, back in a black t-shirt, black jeans and black converse, sounds as raucous and husky as expected, while careful, clear diction is not his forte. And as a conversationalist, he makes an excellent lead vocalist. Why no banter? He uttered a few words  at the beginning of the concert but disappointingly, that was virtually it – except for a call to sing.

The final Melbourne concert is tomorrow night and if it ends up being the final ever, the band will go out with a bang, literally: canon fire to accompany what is a brilliant, inspired finale rendition of For Those About to Rock (We Salute You).

It could be fair to suggest that after losing several original band members, AC/DC survives on the shoulders of guitarist Angus Young. The 60-year-old still looks as naughty and adorable in his red velvet school uniform and cap as he did on Countdown so many decades ago. His duck walk and guitar playing are mesmerising, performing one of the best guitar solos in concert history.

Add a pretty young woman baring her breasts (shown on the giant video screens), scores of blokes and gals with young children trailing (loads of under 10-year-olds) and thousands of people with flashing Angus Young horns perched on their head-banging heads at $20 a pop, and you have the perfect AC/DC concert experience.
