"James Tomlinson's group 'Fount and Origin' work in the field of a cappella polyphony, from Lionel Power to Gesualdo. I had the pleasure of attending their Oxford performance (Merton College Chapel, 9 February 2019) of Ockeghem's Missa Caput, interspersed with motets by Lionel Power. The programme in itself was intriguing, revealing two very different sides of compositional practice in the 15th century. It was hugely commendable to get this music off the ground. However, the event proved to be so much more than an admirable initiative. It was a very satisfying aesthetic experience. The group of some 11 singers handled the challenging idioms with real assurance. Technical and expressive qualities were strong. There was coherence and integrity in their approach. This was student music-making of a high order, revealing a professional approach, and a genuine enthusiasm for this often talked-about but seldom-performed repertory.”
