Duology was formed in the fall of 2017 by Japanese vocalist Chihiro and American bassist Richard Anderson. Their arrangements center on distinct bass lines that set the mood and pulse for each piece with rich with harmonic and rhythmic content. Captivating vocals immerse the listener into the story with melodies that drift along smoothly with great lyrical flow. The use of loopers and effects, plus an intuitive musical rapport, allows the two to reinterpret jazz standards in ways hard to imagine considering the limits of their instrumentation.

Originally from Oregon, Richard started out on piano about age 5 moving to the violin at 9, upright bass at 12, tuba and electric bass at 13. Leaving the violin behind, he went on to study music and began playing in the Portland area from the late 1970s to the mid 80’s.

“In college, I was fortunate to have had teachers that were also working musicians, so they taught from both academic and practical experience—in other words, what you need to know to play your instrument, and what you need to know to make music as a group. They introduced to work opportunities, which turned the bandstand into an advanced course classroom where I could confirm and put to use what I learned in the daytime, gain valuable real-world playing experience, and learn further under some of the best musicians in the Northwest."

Those opportunities led to working with artists such as Rosemary Clooney, Helen O’Connell, Diane Schurr, Nancy King, Debbie Reynolds, Rose Marie, Frankie Laine, Tennessee Ernie Ford, Pat Boone, and more.

Moving to Japan in 1986, Richard has played with artists such as Martha Miyake, Hara Nobuo, Teramasa Hino, Chika Ohashi, Sera Yuzuru and more. He remains active playing, writing, and arranging with his own groups and and backing other artists.

Our original idea for this CD was to record in the U.S. in 2020. As with so many other things, COVID-19 put an end to that plan, so we decided to do the recording on our own in Japan, then have it mixed and mastered in the gained experience, got three tracks together and sent them off for mixing with Bob Stark. One of Bob's first suggestions was to add guitarist David Torn to the Left Alone track. That collaboration led to our Duology+ project. What started out for us as a small, personal project, turned into something much more significant and extremely gratifying on many levels. In May of 2021, the music was released on CD in Japan, and digitally distributed worldwide on Bandcamp.

Jazz is an ever-evolving art form. We started Duology to pursue new, original means of musical expression within the vocal/bass duo format. We hope that many find our music inspiring and look forward to creating more in the near future.
