Hannah is a creative arts marketer and producer based in Shoreditch, with a passion for developing new audiences for classical music. She has experience working with choirs, orchestras, composers, venues, musicians and music charities, leading the marketing campaigns for numerous concerts outside of traditional spaces, including warehouses, pubs, clubs, museums, hospitals and prisons. Specialising in social media, Hannah has managed the digital presence for many music organisations and artists including choral composer John Rutter. Her production credits include classical club nights for Nonclassical and gigs outside of traditional spaces for Street Orchestra Live. Hannah’s alter ego is the Founder & CEO of London Flashmob, creating quirky pop-ups from wedding proposals to cultural pranks, including the London Undersound - a participatory audio adventure through the streets of Soho, which attracted over 1,000 participants.  



"Hannah has been working with us at Team JR for the past year to help us manage John Rutter’s social media profile, and what a difference her involvement has made! Increased followers, more engagement, pushing into a younger, previously neglected demographic – her input has brought fresh ideas and amazing results. We’re so pleased we added her to our team, and would absolutely recommend her services to anyone looking to connect digitally with their audience."

—Joanna Holland, John Rutter & Collegium Records


"I have no hesitation in recommending Hannah. She's a rare talent. A tremendously hard and committed worker and insightful marketer, who led her team at Spitalfields Music to consistently exceed sales and audience development targets through well planned and executed marketing campaigns and by re-energising Spitalfields Music's social media presence - increasing engagement and reach.”

—Richard Scandrett, Head of Marketing and Communications at LAMDA


“Hannah has made a big difference to this small organisation since she started as Marketing Manager at The Old Church two years ago. She is organised, creative and strategic. We have particularly appreciated her commercial awareness and are very happy to recommend her as a sharp, knowledgeable arts marketing specialist.”

—Deborah Coughlin, Artistic Director at The Old Church



hanna Grzeskiewicz

Hanna is a freelance producer and PR, specialising in contemporary classical music. Reflecting her passion for contemporary forms of expression, Hanna is also the Co-Director of the award-winning ensemble The Hermes Experiment, and through this role she has worked with dozens of artists, both within and outside of classical music. Some of her recent work includes producing and managing a tour of George Benjamin’s Written on Skin to the Mariinsky Theatre in St Petersburg, and PR/event management of Nonclassical’s orchestral club night, Rise of the Machines #1 (**** The Times). Concurrent with her passion for contemporary arts is Hanna’s interest in contemporary politics, and she has previously worked as PR Specialist at the Embassy of the Republic of Poland in London. Born in Poland, and having lived in Argentina and Thailand, Hanna currently splits her time between London and Berlin. 



“I've worked with Hanna on a number of projects, including two large-scale tours to the Mariinsky Theatre in St. Petersburg, and I say with no exaggeration that I've never come across a more expert and capable producer. She has a huge amount of experience in everything - from dealing with airlines to building stages to sourcing obscure instruments - and is a fantastic manager of people. However difficult a situation may become, Hanna always keeps a cool head and is able to resolve any issue to everyone's satisfaction, a remarkable feat! None of the projects on which she and I have worked together would have met with even half the success they did had if not been for Hanna's involvement, and I can't recommend her highly enough.”

—Oliver Zeffman, Artistic Director at Melos Sinfonia


Hanna has worked for Street Orchestra Live as tour manager but has also been in charge of press and marketing. In both these positions she has been a fantastic colleague, being quick, innovative and easy to work with. She has found some vital partners for our orchestra and secured a great variety of concert possibilities.

—Gijs Kramers, Artistic Director at Street Orchestra Live
