As Artemis II is currently exploring the dark side of the moon, it seems a fitting hour to make this plea. Of all the pieces of music that I have never heard but long to, top of the list is Priaulx Rainier's Aequora Lunae. Composed for and first performed at the Cheltenham Festival in 1967. It is considered, by those lucky enough to have heard it, her masterpiece. It has never been recorded and is non-existent on the Internet. It has however been broadcast several times over the decades since on BBC radio. As I used to have hundreds of tapes of similar broadcasts, I thought one of the good readers of MWI may have a recording of this piece. I would be enormously grateful until my demise if anyone can put me in contact with a recording of this marvel. Before anyone suggests the British Library, I am not a UK resident and I honestly have no idea if I shall visit the UK again before I die. Thanking anyone who reads this in advance.
