Zipper is the product of years of work. "The tracks on this record began as field recordings taken from Indonesia — insect sounds, gamelan, found sounds," says Kuffner. "Each of these tracks comes from a different stage of my music-writing process over the years. I eventually developed a kind of 'sketch and improv' technique, re-arranging groupings and arrangements of a series of elements. Zipper reflects a culmination of this technique, and in my opinion, it's representative of some of my best work."
