Celebrating Keith McIvor aka JD Twitch aka one half of the mighty Optimo, following news of his passing on Friday 19th September 2025 at the age of 57.
Last month, it was revealed that Keith had an untreatable brain tumour and funds were raised to support round-the-clock care. And now he is gone. My thoughts and best wishes go to Keith's family, friends and loved ones.
Keith was a legend in music for two reasons: his solo work as DJ and producer JD Twitch; then there was Optimo, or Optimo (Espacio).
The latter had two separate and distinct identities. Optimo (Espacio) was a club night that ran in The Sub Club in Glasgow from 1997 to 2010, a partnership between long-time pals Keith and Jonnie Wilkes.
Optimo, or Optimo (Espacio) was also a remix and production duo of Keith with Dave Clark, and which provides a heavy contribution to today's selection. The pair have released countless remixes over the years and it's a testament to the quality of their work that this is just as much about what I had to leave out than what I included.
And Keith's remixes as JD Twitch kept the bar very high, as today's picks will attest.
But that wasn't my first experience of Keith's music, though I found this out much, much later.
In my first forays into downloading MP3s from music sites in 2000 and 2001, I was introduced to Mount Florida via the Matador Records label. I knew next to nothing about, but were subsequently revealed to be a partnership between Keith McIvor and Mike Lancaster. Just five releases between 1997 and 2001 - a 12" of untitled dubs, three EPs and an album, Arrived Phoenix - all excellent.
Today's selection is a tribute to Keith's formidable skills at the controls, redefining trance music for the 21st Century and creating remixes that frequently surpassed the original source song.
I could have gone on and on, but I've restricted my selection to 13 songs and just under 90 minutes. It's not enough, though it manages to span Keith's end of the century excursions with Mount Florida right up to this year's rerub of Primal Scream.
If you're a fan of Keith's music, I hope this serves him well. If you're less familiar with his work, then I hope it inspires you to go looking for more, it's every bit as good as what you'll find here.
Rest well, Keith, you have left so much to savour and remember you by.
