He has played with ensembles such as The English Flute Quartet and the Westminster Camerata, and as a founder-member of the relaxation and ambient music group, Symbiosis.

From 2004, John has been regularly releasing solo albums, taking in classical, folk, and rock stylings.

Since being in Steve Hackett's band together, John and Nick Magnus have often collaborated, recording and performing together many times.

They have performed as a flute/guitar duo across England and recorded two albums of instrumental music, the first of which also featured Steve Hackett.

To support the release of Another Life, a trio was formed with John (guitars, keys, vocals), Nick Fletcher (lead guitar) and Duncan Parsons (percussion, vocals), which was soon expanded to a full band with the addition of Jeremy Richardson (bass, guitars, vocals) and Duncan moving to full drum kit.
