Del Sol String Quartet



Zofo_1Since joining forces as a professional ensemble in 2009, internationally acclaimed solo pianists EVA-MARIA ZIMMERMANN and KEISUKE NAKAGOSHI – ZOFO – have electrified audiences from Carnegie Hall to Osaka Japan with their dazzling artistry and outside-the-box thematic programming for piano-four-hands.  This Grammy nominated, prize winning Steinway Artist Ensemble – one of only a handful of duos worldwide devoted exclusively to piano duets – is blazing a bold new path for piano-four-hands groups by focusing on 20th and 21st century repertoire and by commissioning new works from noted composers each year. 

ZOFO, which is shorthand for 20-finger orchestra (ZO=20 and FO=finger orchestra),also performs heart-pumping duet arrangements of famous orchestral pieces such as Stravinsky’s “Rite of Spring,” exploring the realms in which many composers first experienced their symphonic visions.

Since its inception in 2009, ZOFO has made some remarkable achievements:

  • TWO GRAMMY NOMINATIONS: Best Chamber Music/Small Ensemble Performance and Producer of the Year, Classical, for their first album MIND MELD
  • FIRST PLACE: 2010 Bradshaw & Buono International Piano Competition

  • CARNEGIE HALL concert debut: May 2010

  • FINALISTS: 2011 Osaka International Chamber Music Competition – only piano duo to be elevated to the final round

  • MULTI-DISC RECORDING CONTRACT with Grammy Award winning Sono Luminus Records

Eva and Keisuke are sincerely grateful to the amazing fans, family, and arts granting organizations who have made it possible for them to commission and perform new duet works each year, including their first major commissions from acclaimed composers Gabriela Lena Frank and Allen Shawn.  Based in San Francisco, California, ZOFO is a fiscally sponsored Affiliate of The San Francisco Friends of Chamber Music.
