"A revelation… The Rochdale comic does a fine line in lugubriousness (the accent helps) and has some imaginatively skewed takes on things. Perfectly delivered asides… She’s very impressive” – The Wee Review

"The ultra-cynical Kathryn Mather… used to be a children’s entertainer, and now seems to relish the chance to explore darker thoughts her old job would never allow.  Her black humour certainly hit a chord with the room.” – Chortle

"It’s not controversy for controversy’s sake, it’s deftly handled and occasionally veers towards surreal.” – Cup of Beans

"Mather, whose material is dark, sharp, largely unprintable and often downright bizarre. Her set was a crowd favourite, managing to never offend while delivering no-holds-barred material.” –The Oxford Times

"Her delivery is very downbeat in style, but this comes across as naturalistic. The material was well written and it had a fresh feel to it. No one else is doing anything on welding or shipping losses and so this was a welcome change.” – Notts Comedy Review
