Correct Field Name For "Album Artist" ID3 Tag In SoX With LAME

Correct Field Name For "Album Artist" ID3 Tag In SoX With LAME

I've got SoX compiled with LAME, and it works fine, I can make an .mp3
file with common ID3 tags.
But I can't figure out what to call the "Album Artist" field so that I can
specify a value. For example:
sox -n --comment "Title=Sweep" --comment "album_artist=ALBUM ARTIST TEST"
input.mp3 synth 3 sine 20-20000
Will properly make a file that sounds like a sweeping sine wave, and the
ID3 title will be "Sweep". But the Album artist field is still blank. I've
tried several variations, to no avail:
band bandname albumartist album_artist group orchestra accompaniment
soloist performer leadperformer TPE2, which is the technical name in ID3
for the field I'm trying to give a value.
But none of them seem to work. Does anybody know the right "name" to use
for this value?
