Anthony Pateras‘s music ranges from threadbare ensembles, to theatrical vocal pieces, to solo piano. There are several MP3s of his work at his website, anthonypateras.com, including two from the trio in which he plays prepared piano, along with Sean Baxter on percussion and David Brown on prepared guitar. “Ataxia” (MP3) and “London Two” (MP3) are rattly excursions into group improvisation, the latter especially recommended for its deeply sublimated energies. It’s rare to hear three musicians work so hard to achieve such quiet results. There’s also an excerpt of a solo prepared piano piece, “Chasms: Residue” (MP3) — interestingly enough, it’s downright orchestral relative to the restraint of the trio efforts.
