Morton Subotnick re-mixes original materials of his prophetic and unprecedented late ’60s  electronic music classic “Silver Apples of the Moon” with kinetic imagery by video artist Lillevan tonight (April 7) at the Rubenstein atrium of Lincoln Center – as detailed in my column in City Arts – New York. It’s free as part of the 11-day Unsound Festival, an extraordinary schedule of new and unusual multi-media works presented by the Fundcja Tone of Krakow with the Polish Cultural Institute in New York and the Goethe-Institute New York. Subotnick performs again tomorrow (April 8) at Greenwich House Music School (also NYC), 6 pm.
