Whether you’re walking down the aisle, marking a special moment, or hosting a celebration to remember, JAM Duo bring the beauty of live music to every occasion.
Who We Are
Based in the South Cotswolds, Jules and Anne-Marie are the award-winning musicians behind JAM Duo. Both are professionally trained performers with university music degrees and performance diplomas across multiple instruments.
Together, we travel the length and breadth of the UK — from Cornwall to the Scottish Highlands — bringing elegant live music to weddings and special events of every style and scale.
“Your Day, Our Vibe.”
JAM Duo blend timeless classics and modern hits, creating a soundtrack that feels both stylish and personal.
Our Music
Our ever-growing repertoire spans everything from classical favourites to contemporary pop, rock, and film themes — all beautifully arranged for piano and cello. Whether you’re dreaming of Bach or Beyoncé, our live performances create a unique atmosphere that enhances every moment.
Our current library contains over 18,000 musical scores, but you’ll find over 340 inspirational recorded tracks to explore on our Listen Page — a perfect starting point for choosing music that feels just right for your day.
How JAM Duo Began
The name JAM Duo simply comes from our initials — Jules and Anne-Marie (J.A.M.).
We met through music in 2019 and, during the lockdowns of 2020, began collaborating virtually. What started as remote recordings soon evolved into a shared passion for performing together, and JAM Duo was officially born. Since then, we’ve become one of the UK’s most recognised and respected piano and cello duos for weddings and events.
Our Promise
Every performance is personal. We don’t use stand-ins or deputies — it’s always us, Jules and Anne-Marie, performing live at every booking. From your ceremony entrance to the final encore, we bring professionalism, warmth, and genuine joy to each event we play.
Jules Addison – Piano / Keyboard
Jules began playing the piano at just three years old and soon progressed through the ABRSM grades, achieving Grade 8 on both piano and organ by the age of fifteen. He studied with renowned jazz pianist David Rees-Williams at Cranleigh School, later reading Music at Royal Holloway, University of London, under the mentorship of Jeremy Filsell.
Alongside his academic studies, Jules gained professional qualifications in organ performance and worked extensively in the recording industry — producing and engineering choral and orchestral recordings, and contributing to projects in film and television.
As an organist Jules has worked with choirs across the UK and accompanied services at most English Cathedrals including Canterbury, York Minster and Durham.
Today, his focus is very much on performing with JAM Duo. You’ll usually find him behind his iconic red Nord Stage Piano, sharing a stage (and many miles on the road) with Anne-Marie.
Anne-Marie Humphries – Cello
Anne-Marie’s musical journey began at the age of six with the piano, soon expanding to include the cello and clarinet. A lifelong lover of choral music, she performed in chamber choirs at prestigious venues including St Paul’s Cathedral and Notre-Dame, Paris.
After completing a Music degree at the University of Sheffield, studying under Yolanda Wrigley and Kathryn Harris, she went on to gain a PGCE at the University of Bristol and enjoyed a rewarding 16-year career as a music teacher and Head of Department in Bristol and Gloucestershire.
In 2020, Anne-Marie made the leap to become a full-time performing musician — a decision that gave rise to JAM Duo. Her expressive playing and warm stage presence are at the heart of our sound.
