OK.
This thread is really ignored now compared to when I first started posting a decade ago.
Anyway I know a few here (including myself), like Hammond B3 jazz players., Jimmy Smith, who revolutionized the instrument’s role in jazz, along with Wild Bill Davis, Jack McDuff, Big John Patton, Dr. Lonnie Smith, and Joey DeFrancesco to name a few.
That said, I have been listening to Deep Purple for a couple hours now and Jon Lord, the organ player who was a founding member of DP, along with Ritchie Blackmore, is an incredible organ player.
When I was 22 years old, in 1985, I had the privilege of seeing DP mark II lineup for their one and only reunion tour after they released the album "Perfect Strangers". Jon Lord did a 15 minute organ solo (he was surrounded by a horseshoe of organs/synths towering above him), and it was awesome.
Back on topic! I love jazz that uses the organ! But.... here is a short video of Jon Lord. God Bless and R.I.P.
