I had read the number of Adele new albums being pressed was more like 750,000.
I remember this famously happened with CD pressing plants in 1985 with Dire Straits “Brothers in Arms”
This will continue to be a problem until record companies invest in building new LP pressing plants but unfortunately they don’t seem willing to do so… Vinyl is still a niche market accounting for a small share of record company profit but how can it grow more without more pressing capacity?
