Australian organist Calvin Bowman is set to perform an incredible feat: playing 16 hours of back-to-back Bach organ music for the third time. This Sunday, starting at 6am, Bowman will tackle Johann Sebastian Bach's entire catalogue of organ works on the massive instrument at the Queensland Performing Arts Centre (QPAC) as part of the Brisbane Festival.
The Physical and Mental Demands of a Bach Marathon
Playing the organ is not for the faint-hearted. When Bowman really gets going, both hands fly across the keyboard in different directions while his legs pump away, each foot playing a different part on the pedal-board. During pedal solos, he has to hang on to the seat to avoid falling off. We don't typically think of organ players as athletes, but maybe we should: the level of dexterity, coordination, muscular control, and core strength involved rivals many sports.
This Sunday, Bowman adds endurance to the list. Across 16 hours, he'll play Bach's complete organ works, back-to-back, on QPAC's behemoth instrument. It's a free concert and the third time he's performed this feat, after performances at the Melbourne Festival in 2009 and Mona Foma in Launceston in 2022. The Melbourne performance was so physically arduous it took him a week to recover. "I could barely move, all my muscles seized up … I was hobbling about like an old man," he says.
This time, the 54-year-old will have a masseur helping him with his upper and lower back from the afternoon onwards, during brief breaks. But the real work, Bowman says, is in the brain: "One hand [is playing] a singing melody, and I have another part in another rhythm, and another part in another rhythm, and the pedals are doing something else again. It's like patting your head and rubbing your tummy while reciting poetry."
Calvin Bowman: A Musical Athlete
Calvin Bowman is no stranger to pushing boundaries. As a composer and organist, he has earned a reputation for his virtuosic performances and deep interpretation of Bach's works. His previous marathon performances have been hailed as both insane and inspiring. "It is insane," Bowman admits, "but it's also deeply rewarding."

The organ he will play at QPAC is one of the largest in Australia, with thousands of pipes and a complex console that requires immense skill to master. The instrument itself is a testament to the grandeur of organ music, and Bowman's ability to command it for 16 hours straight is a testament to his dedication.
