Beethoven’s Favourite Guest director Lorenza Borrani and the Australian Chamber Orchestra’s crystalline textures and well-defined sectional balances insightfully illuminate the full range of Beethoven’s inner-voice details. This arrangement proves especially effective in the quartet’s two great slow movements. Sustaining a well-blended ensemble sound and expansive phrasing, the performers astutely judge both movements’ expressive peaks and troughs to achieve compelling moods of rapt quietude. Schubert’s Five Minuets with Six Trios, D89, provide an elegant segue between Schnittke and Beethoven. Llewellyn Hall, William Herbert Place, Canberra. Tonight only, 8pm. Tickets: $43-$137. Bookings: 1800 444 444 or online. Duration: 1hr 45min, including 20min interval.
