Displaying Post (custom types) by Recently uploaded

I am building a website around a database of vinyl record information. Thousands of records have been uploaded as posts. These are custom posts of different categories- artist, album, release. There is a hierarchy already in place where an artist is the parent to album, which is the parent to release.

What I want to do is display these posts. I’m not sure exactly how to word what I’m trying to do.

On the homepage, I want to show the most recent uploads in containers. I have containers set up to display static examples of what I’m trying to do, but I don’t understand how to code in “autofill with newest results”.

I want to $_Get_Releases (most recent uploads)
for each upload
display photo
display artist name and release title

How do I word this in my php files? Thank you, forgive my ignorance, I want to learn!
