Chilvers has collaborated with Eno on several iPhone, iPod Touch, and iPad generative music applications: Bloom, Scape and Air (available on the iTunes Store).
Other participants have included Theo Travis, Tim Bowness, Sandra O'Neill, Steve Adey and Cambridge experimental-country guitarist Rob Jackson.
As Tim Bowness/Peter Chilvers, they released an album of dark reflective ballad songs – California, Norfolk – and an online only remix CDR, Overstrand.
Chilvers has also collaborated with No-Man (playing piano for their comeback appearance at the Burning Shed Evening in June 2006, and contributing "space bass" to the album Together We're Stranger).
Chilvers' other musical collaborations include work with songwriter Paul Goodwin and Underworld's Karl Hyde (for whose live band he plays keyboards).
