Thoroughbass is an early music ensemble whose members play period instruments, but who have trouble staying in the past. Established in 2009 by director and harpsichordist Diana Weston, we love to perform contemporary music as much as old - giving new sounds to music of the present and recent past, while staying true to our early music background. The result is varied, innovative and original programming that dares to step outside the expected square.

We now have a number of recordings to our credit, all available from the website. In addition, Diana’s interest in poetry and art has resulted in some gorgeous productions – a toddler’s introduction to music with Magpie Baby Book and CD and a soon-to-be-released ebook Backyard Friends.

Concerts 2018

Three individual and very different programs are on the agenda for 2018


Soloist for Elizabeth Jacquet de la Guerre’s cantata Semele is soprano Anna Fraser, much-valued and long-time member of The Song Co. as well as Thoroughbass.  The myth tells of the fiery destruction of Semele, loved by Zeus, but unable to resist challenging the truth of his godly nature. Trio Sonatas by Rebel and Marais, performed by Stephen Freeman (violin), Shaun Warden (violin), and Shaun Ng (viola da gamba), round out this all-French program.

Latino Love Affair

A mix of contemporary and early music, with Latin overtones. Now a regular visitor to Australia, Michael Tsalka returns for another season performing concerti, duos and solos by composers from round the world – Toia, Piazzolla, Escande, A. Scarlatti, JS Bach and many others, Support on the ground comes from Thoroughbass’ violinists Shaun Warden and Shaun Ng, viola player Tara Hashambuoy, cellists Lucy Cormack and Angus Ryan, and harpsichordist Diana Weston.

Bach’s Gamba Sonatas

Shaun Ng’s combination of nuance and virtuosity in his performances for Thoroughbass is highly appreciated by all and sundry. With harpsichordist Diana Weston he explores the complexities and intricacies of Bach’s three sonatas for gamba and harpsichord, a big undertaking but one he relishes. Undoubtedly, with these and the Chromatic Fantasia and Fugue for harpsichord, Bach takes polyphony to a whole new level.
