I'm  a  jazz pianist, born in Japan and currently residing in Amsterdam, the Netherlands. Before moving to Amsterdam, I had lived in New York for 7 years. No matter where I live, no matter whom I play with, despite the differences of nationalities, cultures and backgrounds, we always find common ground in jazz music - improvisation.

Recorded, mixed & mastered by Frans de Rond (mixed at Muziekcentrum van de Omroep in Hilversum)

“A Saxless ode to John Coltrane – Bassist Tony Overwater and pianist Atzko Kohashi perform John Coltrane’s music. It is daring to perform Coltrane's music in a duo setting without saxophone, but it works. The beauty is in Overwater’s interpretation of Jimmy Garrison’s bass solo in Lonnie’s Lament, where Kohashi supports him with her smoothly curling pian o playing.”                                  -Gijsbert Kamer, Volkskrant in The Netherlands

“It becomes clear that this duo is musically extremely successful, it sounds as if they have been playing together for years, and the tranquility and suppleness are pleasant to the ear. Lonnie’s Lament is without a doubt one of the highlights of the album. Wonderful!             -Jan van Leersum, Rootstime in Belgium

“Kohashi and Overwater have managed to absorb the spirit of Coltrane's music and implement it in their own individual way. All the songs radiate a great and soothing calm. I feel at the same time connected with the spirit of Coltrane's Crescent.”                                        -Wolfgang Giese, Musikansich in Germany

I believe that the beautiful melodies of jazz—like traditional folk tales— have been passed down from generation to generation. I am happy to be one of those storytellers.                                                                               —Atzko Kohashi
