Laurence Dreyfus, the founder of the viol consort Phantasm, sees John Jenkins (1592-1678) as a relentless explorer, a man daring to venture into harmonic territory that would remain largely unexplored for centuries. He has learnt, says Dreyfus, "to transpose himself and his listeners to exotic locations without standing in wearying queues or undergoing tiresome security checks". Dreyfus's sleevenote provides an insider's colourful view of Jenkins's excursions, some of which are daring enough to take the floor from under your feet, musically speaking. The best way to know this music is to play it. Phantasm's lucidly balanced, cogently demonstrative performances have an intimacy that easily outclasses most public concert experiences of this complex yet ravishing music.
