The AC/DC reunion rumour mill is officially in full swing. The band broke their two-year social media silence this morning, posting a video in commemoration of the 40th anniversary of their seminal record Highway To Hell.

AC/DC had not posted anything on Facebook since November 2017, announcing the passing of iconic rhythm guitarist Malcolm Young.

The band have now announced through their social media channels that they will be celebrating 40 years of Highway To Hell all month long. This morning the band shared a 1979 performance of the records titular track from their appearance on Countdown, which you can watch below.

This sudden social media activity comes after a week of rumours reaching their groundswell that the band were gearing up to announce a reunion tour. 

Whispers that the band were getting together again peaked after US radio station V100  announced that “sources” had revealed that the rock monoliths were gearing up to announce a stadium tour in the coming weeks. The station has also claimed that frontman Brian Johnson has rejoined the lineup.

Last August, rumours began circulating that Brian Johnson had rejoined the band after Johnson and drummer Phil Rudd were photographed outside a Canadian recording studio where AC/DC had produced their last three records.

LA grindcore band Terrorizer added fuel to the fire after claiming they ran into Brian Johnson at an airport; who apparently confirmed that he had rejoined the band.

Johnson announced his retirement from AC/DC back in 2016 after he revealed that he was suffering significant hearing loss after decades playing in one of rock’s loudest bands.

“I cannot imagine going forward without being part of [AC/DC], but for now I have no choice,” explained Johnson in a statement at the time. “I wish to assure our fans that I am not retiring.”

Following his departure from the band 2016, Brian Johnson was replaced by Guns N’ Roses frontman Axl Rose.

Highway To Hell was initially released on July 27th, 1979. It was AC/DC’s final record with original vocalist Bon Scott, who passed away in 1980.

We don’t want to count our chickens before they hatch, but we hope that the climax of this month-long celebration of one of the most iconic records in rock’n’roll history culminates in the band announcing the long-rumoured reunion tour.
