I also listened to Olivia Chaney, a good singer and a multi-instrumentalist (and in my view loads better than Loreena McKennitt). Is her music New Age? I have never really understood what New Age music is, New age is a philosophical outlook derived a bit from Theosophy, but I am not really sure how it came to be a musical genre. It seems to mean music which sounds a bit like Enya, or maybe something involving William Orbit.

I don't see how her music can be thought of as any kind of Jazz, even Light Jazz (and definitely not Lite Jazz). Jazz is an American form and Olivia Chaney is definitely an English singer.

She sings songs by writers usually thought of as folk artists, such as Bert Jansch, and she sings them in a bit of an MoR way. I though a bit like Vashti Bunyan, though better on the instruments.
