July 2017.

This was the very talented Matthew Siveter. His entrance had myself and the people sitting next to me, wide eyed and open mouthed. On to the stage came a tall, slender man dressed as though he was part of a 1980's glam rock band, whilst also being in the starting line-up for the part of 'The Rum Tum Tugger'. However, once he began to sing this deep, powerful voice boomed into every corner of the auditorium. His facial expression and subtle hand gestures only added to everything he did. Love it.'

http://gsfestivals.org/content/join-our-new-year-weekend-grims-dyke-2-4-january-2016 Our Festival youth programmes have spotted a number of potential stars of the future. Matthew Siveter is a great example. Matthew played Mountararat in this year's University production and will present his own show: Topsy Turvy - A Musical Extravaganza in Gilbertian Fashion (accompanied by Martin Yates).
...As too was Matthew, one of the youngest on stage, but one of the tallest as well. You couldn't mistake him in the crowd of pirates. G&S is in his blood as he has been performing their works from the age of twelve. He looks like he's having fun on stage and I'm sure that he is and that floods over to the audience, making sure that we have as much fun watching him...."

HABEAS CORPUS by Alan Bennett - Retford Little Theatre 19th-27th November 2010 - Dennis Wicksteed played by Matthew Siveter
http://charispayne.tumblr.com/post/67947225954/royal-holloway-musical-theatre-society-presents Another highlight was Matthew Siveter’s rendition of Dentist!, which I belly-laughed my way through. Performed by Steve Martin in the film, this song is a challenge to pull off well, but Siveter had excellent characterisation and impressive vocal prowess. Whilst it was obvious that Siveter was trained to sing operatically, he embodied the Little Shop style successfully to absolutely deliver a belter. Only in his first year at Royal Holloway, Siveter will be one to watch in the university’s performance scene.
