Tycho (pronounced like Tie-ko, with emphasis on the first syllable) is an American ambient music project led by Scott Hansen (born 1976 or 1977) as primary composer, songwriter and producer. Hailing from San Francisco, California, he is known as ISO50 for his photographic and design works. His music is a combination of downtempo vintage-style synthesizers and ambient melodies. The style of his music is very organic, typically incorporating clips of the human element into his songs (i.e. weather broadcasts, simple talking, or even breathing).
