The album, ‘Hammer Inventions’ by Lynda Arnold and Daniel Berkman features piano compositions and layered electronic orchestrations made entirely of sounds generated from the piano. From delicate and ethereal acoustic piano moments reminiscent of George Winston or Philip Glass to layered textural moments similar to Steve Reich, or Autechre, Lynda and Daniel create new pieces within the limits of piano-generated sounds. What emerges is a fresh take on the instrument, both as a collaborative, skilled piano duo and as seasoned electronic music production artists. Some of the piano sounds used include prepared piano (John Cage homage), plucked piano, bowed piano, toy piano, backwards piano, detuned piano and more effected and sampled expressions. The project was born out of a spontaneous piano four-hand improvisation session and grew from there. After a dozen piano writing sessions, Daniel and Lynda went into the studio to start recording the compositions while at the same time dreaming up ways to incorporate other unique sounds like sticking screws and bolts in Lynda's Yamaha piano to create drum sounds, plucking the strings to make a sampler of plucked piano notes and a bowed piano library by Sonic Couture to add more sustained, string like sounds to layer the arrangements. The acoustic piano recordings where done at Broken Radio studios on George Winston’s Yamaha C7 piano in San Francisco with the help of engineer Matt Boudreau. Hammer Inventions is slated for official release in Fall 2011 with live performances to follow.
