From what I have heard live, in my opinion, 2023 has been marked by these artists in the widest possible range of their concepts and collaborations including their 2023 recordings.

Fred Hersch and Esperanza Spalding (diverse creative concepts; North Sea Jazz, Rotterdam, Netherlands)

Myra Melford (from her latest project to unique colaborations in Saalfelden, Austria and Lisbon, Portugal)

Zoh Amba (various formations and contexts, Saalfelden, Austria)

Kris Davis (MVPlayer, Umbria Jazz Winter Orvieto, Italy, and NSJ, Roterdam)

Brandee Younger (harph back in spotlight and Alice Coltrane's heritage, passionately  and freshly redefined; NSJ, Rotterdam)

Kurt Elling's Super Blue (pulsating party; NSJ, Rotterdam)

Oded Tzur (NSJ, Rotterdam; BJF, Belgrade, Serbia; master of dynamics, draining the wood out his sax)

Isaiah Collier (Belgrade; an  exclamation of "Peace and Love")

John Scofield Uncle John's Band (that being enough, Belgrade)

Ambrose Akinmusire's Owl Song (this colaboration and because of his impact on other mostly younger musicians, becoming an important point of reference)

Henry Threadgill (performance in Berlin, Jazzfest and an impact he has and an inspiration he is for other musicians)

Cecile McLorin Salvant Melusine (meticulous; almost herd her for NYE but I had missed the plane reservation for Rome- Orvieto,Italy)

Bark Out Thunder,  Roar out Lightning by  Chief Adjuah (because of delicately coloured performance of Christian Scott in Belgrade, some years ago, and the way his interests evolve I would like to hear this live. Is it happening anywhere?)
