John Luther Adams' Four Thousand Holes for Piano Percussion (Vibraphone and Orchestra Bells) and Electronic Aura. Composed in 2010 and dedicated to Stephen Drury. Duration: 32 minutes 30 seconds.'Four Thousand Holes is my own effort to re-appropriate and reclaim for myself something of my own musical past. For the first time since my days as a rocker I've chosen to restrict myself to major and minor triads - thosemost basic elements of Western music (both pop and classical). But I've tried to assimilate them fully into my own musical world. Approaching these simple chords as found objects I've superimposed them in multiple streams oftempo to create darker harmonies and lush fields of sound. In recent years I've been fortunate enough to form a close musical partnership with Stephen Drury. Steve's extraordinary gifts inspired me to exploreexpansive forms and textures (similar to those of my orchestral music) with only one or two performers In essence Four Thousand Holes is a concerto. To begin I composed the score for the electronic tracks. Steve recorded all ofthe individual chords that occur in the score. I took these recordings time-stretched them reversed their envelopes and knit the reversed sounds together with their original decays. The resulting waves of sound I layered intoten independent tracks to create the virtual 'orchestra'. Next I composed the Piano part articulating the peaks of all the electronic tracks simultaneously - a feat of coordination that demands considerable virtuosity from thepianist. Finally I composed another multi-layered part for metallic Percussion sounds that I think of as sparks emanating from the Piano. In Four Thousand Holes strong musical currents fall and rise again andagain as points and lines are juxtaposed with heavy hammered chords. The mix of 'live' and electronic sounds blurs the distinction between musical figure and ground. As in much of my recent music I conceive of the entire piece
