Plumunion.

Plumunion was a short lived musical act from Chicago.
It was made up of two members, Edwin Perries, and Cat Ries.
They played ukulele, dinner bells, backpacks, juice harps, themselves, and a bunch of other goodies.
While the music, lyrics, and rhythms were amazing, the real treat was the strange, yet beautiful vocal harmonies.

They released one album they i know of, unofficially titled "too bad we cut it backwards"
it came with a lyrics/poetry book and hand made artwork.
