Kristin Hersh

From the “Downloads” section of Kristen Hersh’s web site:

Every month, CASH Music brings you Kristin’s newest recordings in several formats including lossless audio. For each song, Kristin also provides lyric sheets and a “Works in Progress” demo version of each song. Kristin also offers her songs to the CASH community in “Read-Write” format — by making available her Pro Tools mix stems!

Very clued in: periodical small releases of one song in an interactive format rather than irregular large releases of many songs on a static CD.

I can’t do a remix because I don’t have Pro Tools but I did play guitar along with the MP3 and it was fun. And I found that by engaging directly with the music I actively enjoyed Kristen Hersh’s work for the first time, so there was clearly a promotional effect.
