While not a member, ex-Outsider Adrian Janes would contribute ideas and co-write lyrics to the Sound's music.

[2] The Sound made their debut with the EP Physical World in 1979, released on manager Stephen Budd's Tortch label.

Upon hearing the rough mixes that Budd had financed, WEA sub-label Korova, then home of Echo & the Bunnymen, offered to sign the group, and the band accepted.

[1] Jeopardy, their debut album, was recorded inexpensively and released in November 1980 to critical acclaim; it received 5-star reviews from three major music publications, NME, Sounds and Melody Maker.

[4] Following the album, Marshall left the band and was replaced by former Cardiacs member Colvin "Max" Mayers.

Like their contemporaries the Comsat Angels (whom they toured with in 1981), they enjoyed perhaps their greatest success in the Netherlands, developing a substantial following there.

[6] The Sound recorded a Peel session and performed the single "Sense of Purpose" on the TV show Old Grey Whistle Test.

[1] In 1983, The Sound released a joint EP in collaboration with singer Kevin Hewick, This Cover Keeps Reality Unreal, on Cherry Red Records.

[8] Following the collapse of the Sound, Borland maintained a solo career for approximately a decade, and participated in the side projects Honolulu Mountain Daffodils (under the alias Joachim Pimento)[11] and White Rose Transmission.

[1] Never able to conquer his depression and anguished about returning to a psychiatric hospital, Borland, who reportedly suffered from a schizoaffective disorder, committed suicide on 26 April 1999,[1][12] throwing himself in the path of an express train at Wimbledon station.

[13] Shortly before Borland's death, the Sound's back catalog was remastered and reissued by Renascent, a label which was founded to perform solely that task.

On Black Friday, November 26, 2021, SoundHaarlemlikesVinyl releases a new album 'Will and Testament' with 3 sides of live performances from different gigs.

[16] A biography of Adrian Borland, titled Book of (Happy) Memories (compiled by Willemien Spook and Jean-Paul van Mierlo) was published in 2001.
