Viersen, in the lower Rhine region of Germany, is the setting for the penultimate concert of the 91Èȱ¬ Philharmonic’s tour of Europe. The concert is framed by two 19th-centry works: Rossini’s Silken Ladder Overture and Mendelssohn’s Third Symphony, the Scottish - said to be inspired by the composer’s visit to Scotland in 1829. At the heart of the programme are two technically astounding percussion concertos performed by ‘wizard of percussion’ Martin Grubinger, including the stunning piece Rough Music, by the 91Èȱ¬ Philharmonic’s own Composer/Conductor HK Gruber.
