We can so easily miss new stars rising in the firmament of music composition. But for me, unexpectedly, out of the ether (of BBC Radio 3) dropped a 4-minute jewel of a string quartet, and with a title that was hard to forget, Tide Purl by Liz Johnson. It was played by the Fitzwilliam Quartet as a trailer for a concert to launch 2-CD retrospective including all this composer’s work for the string quartet medium. . I was immediately hooked… [this] is a significant body of English music for string quartet.
