Excerpted edits are rarely Disquiet Downstream fare, but when the fragment is almost four minutes in length, owing to its having been culled from a nearly hour-long CD, then so be it — especially when it’s the likes of Stephen Vitiello‘s exceptional BuffaloBassDelay. The releasing label, Hallwalls, explains where the delicate mix of found sounds originated: “The CD consists of one 54 minute track developed from field recordings Vitiello made while exploring abandoned grain elevators along the Buffalo River in 2003.” The result (MP3) may carry the weight of ambiguous real-world audio recordings, but it’s more than mere atmosphere; they’re mixed into a flush of beady little rhythmic delights. Vitiello recorded the piece while on a Hallwalls Artists in Residence Project, funded by the National Endowment for the Arts and the Andy Warhol Foundation for the Visual Arts.
