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 venue

The 606 Club has been one of the busiest jazz clubs in Europe since 1976, featuring jazz, soul, groove, Latin, R&B, funk, gospel, blues and groove artists with live music 7 nights a week plus Sunday lunches.
