“The three scheduled Keith Jarrett solo concerts in Japan in late-April/early-May are now more or less sold out, so a fourth concert on May 9 has been added in Tokyo at the Kioi Hall which is a prestigious 800-seat classical recital hall.”
The concert has been announced yesterday by Koinuma Music (as a “special night”). Tickets will go on sale on February 23 at 10 AM.
Thanks to Stephen and Håvard for the information.
