It turns out he was a prolific composer as well. Marko Letonja and the Sinfonieorchester Basel have made a new recording of his Symphony No. 7 (CPO 777 103-2) which is an ambitious work for full orchestra, choir and soloists. Perhaps this will mark a turning point in his international reputation. In any event it is a work of great orchestrational command, thematic depth and dramatic impact.
Without sounding like them, Weingartner in his 7th shows some of the largeness of Bruckner and Mahler. It is a work of soaring rhapsody, cosmic mystery and fully fleshed-out grandeur.
The performance is quite impressive, passionate and sympathetic, so we get a very fair hearing. I have no idea what the rest of his music sounds like, but Symphony No. 7 is a winner. Lovers of the symphonic tradition from Beethoven through Mahler will no doubt revel in this recording. Whether Weingartner is here to stay time can only be the judge.
