The band’s Facebook account had been quiet since the death of guitarist Malcolm Young in November 2017, while their Twitter account hadn't been updated since March of that year.
But they’ve now uploaded a short video graphic showing the AC/DC logo and Highway To Hell: 1979-2019 with the caption: “Celebrate with us all month long! #H2H40.” The famous riff from the track also plays over the top of the visuals.
They've also updated their Facebook cover photo showing the shot of the band that was used on the cover of the record.
Last week, V100 Rocks suggested that AC/DC would announce a “2019-2020 world tour” at some point today (July 17) but there’s nothing official yet.
The future of AC/DC has been the focus of much speculation over the last 12 months or so.
In August 2018, the rumour mill went into overdrive when Brian Johnson and estranged AC/DC drummer Phil Rudd were spotted outside Vancouver’s Warehouse Studios where the band have recorded several albums in the past.
They were then photographed with longterm engineer Mike Fraser at the same location, with Fraser later confirming the band have been back in the studio “doing something."
In January this year, Johnson appeared to confirm he was back in the band after his well-documented hearing problems, when he's reported to have told Los Angeles outfit Terrorizer that he had been “sick of denying it.”
