The article mentions that Charlie (Bird) Parker's music is now public domain in most of the world (life + 70 years), but most of his records are collaborations with other artists like Dizzy Gillespie who died much later, less than 50 years ago.

In those cases, how would I know if a record is public domain or not?
Someone would retort that patent is not same as copyright. But really dude that's all just made up stuff by politicians and corporations. In the end Tesla died pennyless and these corporations and entities get to hoard all the human creativity till what it looks like an eternity for my meagre life span.
For example commercial 3D printing (using FDM) was likely significantly stalled until the relevant patent expired.
