One of the first pop recordings made there was the backing track for The Easybeats' 1965 breakthrough hit "She's So Fine", which was overseen by British-born engineer Roger Savage, who had recently arrived from the UK as an assisted migrant.

In 1972 the company bought a former butter factory in Bank St, South Melbourne, and converted it into a five-studio complex, making Armstrong the largest commercial studio in the southern hemisphere.
He went on to work with Julian Menndelson & Trevor Horn, multi-platinum Queensrÿche and won a Grammy Award for Best Live Recording for Eric Clapton's "Unplugged".
Other renowned acts who recorded at AAV in this period include U2, Paul McCartney, Madonna, Bob Dylan, Split Enz, Crowded House and Australian Crawl.
In the meantime Edensound Mastering had taken residence in the famed 180 Bank Street building and directors Martin Pullan and David Drew took the opportunity to take over the lease and return the studio to its original Armstrong name.
After a massive revamp including the installation of a vintage Neve console, Armstrong Studios today continues to be one of the foremost recording facilities in the southern hemisphere.
