Described by The Strad as ‘a mesmerising musical treasure’, and by the London Evening Standard in 2005 as ‘a phenomenal talent’, Gemma’s recording for Hyperion of the complete works for cello and orchestra of Sir Charles Stanford with the BBC Scottish Symphony Orchestra and Andrew Manze was hailed as being ‘superbly played’ (BBC Music Magazine), whilst Gramophone wrote that Gemma ‘plays with disarming character and freshness; her technique too is enviably sure and tone beguilingly rounded’.

Recent and future highlights include Edward Gregson’s Cello Concerto ‘A Song for Chris’ at the Presteigne Festival, Dvořák’s Cello Concerto with the Estonian National Orchestra and Vello Pähn; Elgar’s Cello Concerto at the Royal Festival Hall with the Philharmonia Orchestra under by Christopher Warren-Green and Concello by Maciej Zielinski in Krakow with Sinfonietta Crokovia. Gemma is cellist of both Ensemble 360 and the Leonore Piano Trio, with pianist Tim Horton and violinist Benjamin Nabarro.

Gemma plays on a cello made in Naples in 1704 by Alessandro Gagliano, formerly owned and played by the Prince Regent.
