Bryan has performed in oratorios, operas, musicals and various concerts around the UK and the world, and has made many appearances on radio and TV along with various recordings.

Adjudication has taken Bryan to Hong Kong, Trinidad and Tobago, Gibraltar, Guernsey, most recently Jersey, and all around the UK and Ireland. He encourages his own students to enter festivals at all levels of their development, and in all styles and genres, believing strongly that the purpose of the festival movement is vital for performers - the platform of a safe, supportive and constructive environment in which to practise and to develop one's artistic and performing persona.
