While listening to Last.FM, I discovered a very interesting independent label from Boston. The label is Paper Thin Records and they specialize in instrumental indie, pseudo-outsider, and rock/noise/experimental/8-bit artists.
Here's the artists (linking to their Last.FM page so you can listen to their free streams).
Avi Paul Weinstein
The Georgie Porgies
The Daikon Legs Quartet
Reverend D and the Fifteen Teeth
