JD Twitch, one half of the legendary Scottish DJ duo Optimo, has died at the age of 57.
The DJ, real name Keith McIvor, announced in July that he had been diagnosed with an “untreatable” brain tumour, and on Saturday (September 20), his bandmate Jonnie Wilkes confirmed that he had passed away.
Posting on Instagram, Wilkes said: “It’s with immense sadness that I’m writing to tell you Keith passed away peacefully yesterday at 2.06pm at The Prince and Princess of Wales Hospice in Glasgow.”
“In a 28 year partnership he changed my life immeasurably and together we took our work in directions and to places few people are lucky enough to explore. I am forever grateful for everything he bestowed on me, both as a partner in music and as a friend. Keith’s intensity and passion for life, for music, for creativity and for positive change simply never let up. He was formidable. His belief in people and the idea that standing together, that our collective strength is powerful was unwavering. I loved him for that.”
“My thoughts are with Keith’s family and friends,” Wilkes added. “Thank you to them and the extended group who have tirelessly supported Keith and each other in the last few months. Thank you to the staff at The Hospice who made this last while as good as it possibly could be. Keith left us far too soon. He will go now to travel those space-ways but I know his energy remains in every one of us who had the privilege of knowing him. I love you forever Keith.”
McIvor grew up in Edinburgh, where he co-founded the influential members-only club night Pure, which established his reputation for genre-fluid programming. He launched Optimo with Wilkes in 1997 at Glasgow’s Sub Club, creating a legendary, boundary-pushing Sunday night residency that employed a diverse music policy.
The duo began touring worldwide and launched the Optimo Music label, which supported and promoted adventurous new voices in music. McIvor also produced acclaimed mixes and film soundtracks that further highlighted his deep musical knowledge and curiosity.
