Sonnerie's core group consists of four musicians:

• Monica Huggett: violin
• Emilia Benjamin: violin, viola da gamba and viola
• Joe Crouch: cello and viola da gamba
• Matthew Halls: keyboards

These four form the basis of the larger chamber ensemble while also functioning as a flexible smaller unit, performing trio sonatas, quartets and the like.

Sonnerie has just released a recording of Heinrich Ignaz Franz von Biber (1664-1704) violin sonatas for the ASV label. The music is very free ranging and fantastical, as well as being technically more demanding than anything that has been written for violin up until that point.

Another recent release is the Mozart Piano Quartets, with Gary Cooper on the fortepiano. This includes the first ever recording of the contemporaneous piano quartet arrangement of the quintet for piano and winds. This was almost certainly made during Mozart's lifetime as there is musicological evidence that the piano quartet ending, which is different from the piano and winds, is in fact a transcription of a first draft which is in the Bibliothèque Nationale in Paris, in Mozart's autograph.
