When I listen to Elgar, I hear what it's like to be me. I hear the uncertainties, the passions, the dreams, the attempts ... it's difficult to explain, but it is music which is inside me. Mark Elder called Elgar "the English Mahler". I find Elgar's treatment of the orchestra to be remarkable. He learned orchestration by playing second violin in Midland orchestras, by studying scores and by knowing about the basics of playing of just about every instrument in the orchestra (one of the benefits of growing up in a family which owned a music shop). He received no formal musical education - what you hear is pure Elgar.
I heard VW 5 a year or so ago. Wonderful piece - superbly handled by John Wilson - but it struck me as being intense rather than passionate. The same concert included Elgar's Sea Pictures. Nowhere in the VW symphony, though, is the darkness found in the Elgar.
I love the music of both composers - but Elgar a little more.
