Guy Retallack - Director

I was lucky enough to work with Rob Summers during the summer of 2021 on John and Jen by Andrew Lippa and Tom Greenwald. 

John and Jen is a two hander musical with a band of five, and moves from sung through sections, to intense dialogue scenes.

The play is episodic, swiftly moving through time and space, and needs a nuanced ear and eye to capture all these changes. We had an experienced team, expertly brought together by Leon Kay and Michael Bradley of Bray Productions, and we were extremely fortunate to have Rob Summers as the key component to bring the sound dynamically to life. 

Mixing a live band of 5, in the confines of Southwark Playhouse’s 120 seater studio, making the sound dynamic and enveloping, a moment later drawing the ultra close audience into the fine emotional detail this intensely moving familial story demands, takes a very nuanced ear; being able to recreate this tiny dynamo of a show every night, matching the powerful singing voices of Rachel Tucker and Lewis Cornay with quietly spoken intimate exchanges takes a practitioner of enormous skill: 

Rob achieved all the above effortlessly, and was a lovely man to work with, unfailingly polite, courteous, warm and funny, you couldn’t ask for a better work partner.
