Matthew also composes under the name John Heath. These are largely choral works including Nova! Nova!, which was first performed in Durham Cathedral in 2014 and The Coventry Carol, first performed in 2013 by Grey College choir, Durham.
If you ask Matthew about John, then, for some reason, he will insist on talking about him in the third person. Still, referring to yourself in the third person is all the rage. Or so he hears.
