Blake-Plock's musical work includes elements of folk and blues as well as free improvisation, electronica, and unorthodox recording techniques.[2] His early work consisted “almost entirely of rudimentary home recordings of songs committed to tape as they were being written, never to be refined or recast. Partially inspired by the field recordings of Alan Lomax, Blake [used] a one-take method to get back to the essence, as he sees it, of folk music, which once hinged on a much closer relationship between audiences and those who made it. In this light, his works-in-progress can be seen as a rather unpretentious attempt to rehumanize (and even bring the 'folk' back into) folk music."[3]
Around 2004, Blake-Plock's work took on a more wholly improvised quality seemingly inspired both by European Free Improvisation as well as American noise and performance art. Blake-Plock's 2007 album The Violencestring is a musical narrative consisting almost entirely of free improvised music and studio manipulation.[4]
