The Crash Ensemble, which has been enlivening the new music scene in Ireland for over two years now, makes its first appearance at the Temple Theatre in Dublin tomorrow night. The programme is a typical Crash mix, works by group members John Godfrey and Donnacha Dennehy, a repeat of Stephen Gardner's Mutable Sea (premiered last year, when Gardner was composer in residence to Dun Laoghaire - Rathdown Co Council), Steve Reich's Vermont Counterpoint for flute and tape, and works by Iannis Xenakis and William Brooks, two composers new to Crash's repertoire. Also this week, the Cyprus-born British pianist Martino Tirimo plays Beethoven and Chopin at the NCH John Field Room on Thursday. And on Friday at the NCH Alexander Anissimov conducts the NSO in a programme of Kodaly (excerpts from Hary Janos), Liszt (the Second Piano Concerto with Finghin Collins) and Bartok (that haunting opera, Bluebeard's Castle, with Fassbender and Storoziev).
