Heard this piece ("Sleep") yesterday on ClassicFM, so searched for it on YouTube. There are a number of videos; here is one.
This reminds me that I heard his "Lux Aurumque" some time ago and made a note to buy it some day. (I think I may have ordered it from Britannia Music Club, but then they went bust.) Here is the composer conducting it in a recording session.
Both are on this CD:and can be bought here: Amazon or CastleClassics.
