It's peculiar how certain things turn out: On Friday, the principal conductor designate of the Ulster Orchestra, Thierry Fischer , conducts an all-Irish programme which, with four works, will leave him just one work behind the tally notched up by Alexander Anissimov. Fischer's Ulster Orchestra programme, a free, BBC invitation concert at the Ulster Hall, offers Sean O Riada's finest work, Hercules Dux Ferrariae of 1957, Charles Villiers Stanford's 1919 Irish Concertino for violin and cello (Fionnuala Hunt and Aisling Drury Byrne giving what's probably the premiere of this unpublished piece), Philip Cogan's Piano Concerto in C Op 5 of 1790 (with Hugh Tinney), and Hamilton Harty's 1910 orchestral poem, With the Wild Geese.
