The smart home sound systems leaders were joined by Goldie and The Libertines' Carl Barat as they celebrated the life of David Bowie and honoured his work and legacy at the store in Seven Dials, Covent Garden, London.
The event - which was hosted by Miranda Sawyer - saw Goldie, Carl Barat and Rostam speak about how they were influenced by the late musician, sharing their stories and the songs they felt fitted the story best.
The Klaxons' Jamie Reynolds, Radio 1's Huw Stephens, 6 Music's Matt Everitt, Colleen Murphy, Kate and Lee Tiernan and Twiggy Garcia were also in attendance.
Cultural commentator Paul Gorman also curated a display of rarely seen images of David Bowie
The event was to celebrate the new Sonos One, their first-ever voice activated speaker.
Whitney Walker, general store manager at Sonos, had said of the store previously: "The entire store experience is based on the idea of being in a really comfortable and inspiring environment. We have carefully considered how people bring music into their home environment through curation, and used it within the concept store to pay homage to the great city of London and the culture that was born here and continues to inspire the world."
