I had the privilege of seeing Dr. Lonnie Smith live a dozen times at various NYC Jazz venues. A couple of times with Lou Donaldson as Lou and Lonnie collaborated on a few album recording sessions.
I also would check the NYC Jazz venues for Donaldson residences and would still be going to see Lou if he did not retire a few years ago. Lou is 95 years young!!
Dr, Lonnie Smith was named the year’s best organist by the Jazz Journalists Association nine times.
Here is a really good Downbeat Magazine article published the day after the Doctor passed away
In Memoriam: Dr. Lonnie Smith, 1942–2021 (downbeat.com)
@Mahgister I can recommend some Lou Donaldson and Dr. Lonnie Smith recordings if you are interested.
Here is one they collaborated on and its a really funky fun jam session featuring the great George Benson on guitar.
