This year marks 50 years since the passing of the great John Coltrane (and 10 years since that of his wife Alice Coltrane). On 18 November, a special commemorative concert is to be held at The Barbican in London.
It features a rare London appearance by Pharoah Sanders (hopefully accompanied by pianist William Henderson) with Denys Baptiste and Alina Bzhezhinska also performing on the bill.
The concert publicity says it will be:-
A three-part journey through the cosmos, celebrating the profound musical and spiritual legacy of two of the most influential figures in Western musical history: Alice and John Coltrane.
When I checked the Barbican Box Office on 25 August 2017, the concert had sold out.
