"She sings, she draws, she does voice acting and imitates characters! The spectacular British multi-talent, EileMonty is here to talk about everything she does. But is there anything she can't do? Come to the panel and find out! We will also get a glimpse into her work and maybe hear about what she is working on at the moment. And like with any great panel, the audience will also have an opportunity to ask her questions."

Find me elsewhere!
