mpd mpc query language

Question

I can't figure out how to properly query mpd using mpc.

For example: I know how to list all albums

mpc list album

But I want to get more than the name.

How can I query mpd for album, path, artist, track number, duration and so on? Preferably in one query but multiple queries are ok as well.

I tried to read the mpc man page and the official documentation of mpd but can't figure it out.
