About Estill Voice Training

Estill Voice Training (EVT) is a scientific, evidence-based system for vocal development. It is a life-changing approach that can help you become a stronger and more emotional performer by giving you effective tools to improve your craft. With EVT, simple everyday sounds are used to identify structures in the larynx and in the vocal tract (i.e. throat, mouth and nose). These are then trained in detail to give conscious, predictable and reliable control of your voice. 

About the pianist

He has played with visiting American artists Al Jarreau, Marlena Shaw (Ronnie Scott’s club residencies,) Benny Golson, Phil Woods, Grant Stewart, Sheryl Bailey and in groups led by leading UK artists Jacqui Dankworth, Stacey Kent, Claire Martin, Dave O’Higgins, Steve Fishwick, Allison Neale, Anita Wardell, Georgia Mancio and Jean Toussaint. Rob was also a member of the award winning group Kairos 4tet. He regularly appears with the BBC Big Band and Ronnie Scott’s Jazz Orchestra.
