It appears there's been a misunderstanding in your request. From the list provided, there's only one John Gilmore associated with music, specifically John Gilmore (musician) (1931–1995), who was an American jazz saxophonist. His contributions were significant in the jazz genre, rather than electronic or dance music. However, I can certainly rewrite a biography focused on his music career for a general music discovery platform context:
John Gilmore, an American jazz saxophonist, carved a niche for himself in the world of jazz from the 1950s until his passing in 1995. Known for his innovative approach and technical prowess on the tenor saxophone, Gilmore was a central figure in the avant-garde jazz movement. His tenure with Sun Ra's Arkestra, where he served as both a soloist and a reliable ensemble player for over four decades, solidified his status as a key influencer in jazz's evolution. Gilmore's unique sound and improvisational style not only contributed significantly to the Arkestra's eclectic output but also inspired future generations of musicians, including prominent figures in the electronic and dance music scenes. Though not directly involved in electronic music, Gilmore's legacy lives on through the artists who cite his adventurous spirit and boundary-pushing techniques as a major influence on their work.
