mpc does not have (at the time of writing, v0.27-1) commands that give you all the metadata for the song identified by uri. Surprisingly, this is not so, but it is not.
The MPD protocol, however, returns complete information about each song.
If I issue mpc current , I get only this answer:
Afro Celt Sound System - Release
However, if I send the currentsong MPD (not MPC) command, then I get this response from MPD:

I personally use the ruby-mpd library to provide a convenient interface for communicating with MPD in a rich, full-featured way.
