As different combinations of eight players took the stage, we already knew that, whether it's duo, trio, quartet, nonet or full ensemble of eleven, sublime intoxication is guaranteed. These musicians don't just pour heart and soul into their music-making, they become one with the music, and, through the perfect balance, blend and synchronisation of every individual's energy, enthusiasm, virtuosity, sensitivity and emotion, the listeners are wrapped in a unified flow of sound that floats them off to heaven.

Tonight's programme was enthralling and varied, as always. Beethoven's Horn Sonata was warmly welcomed, Naomi Atherton presenting a sturdy, resonant, melodic piece, which the composer, like many a musician, didn't get round to writing until the day before famous virtuoso Giovanni Punto was to perform it, yet still managed to provide the piano with a heap of impressive, racy work.

Two beautiful and exciting pieces showcased the amazing singing oboe of Adrian Wilson, whose great warmth and depth were complemented again by the fine pianistic skills of Tim Horton. We were treated to Poulenc's beautiful, tuneful lament in Sonata for Oboe and Piano and Gerald Finzi's stunning Interlude in A Minor. As Finzi's final notes of sad beauty echoed in our ears into the interval, we felt doubly indebted to him, having learned that he also helped ensure the survival of several varieties of English apple!

Now, Schubert's Quintet in C (D956), even if you refuse to be tickled by his Trout Quintet, is such a different kettle of fish, it truly thrills, especially when played by the awesome strings of Ensemble 360 , enhanced by the deep splendour of double bassist Laurè ne Durantel. The colossal breadth and variety of this piece allowed the swaying players to hold us spellbound with perfectly unified bursts of loud, fiery turbulence, with passionate, exuberant flourishes, and with delicate, velvety nuances of touch and timbre that took us to heights of plaintive, sublime beauty, the likes of which Inspector Morse could only dream of.

We must make the most of this extraordinary blend of outstandingly talented people while we can. Because they unfailingly knock the socks off South Yorkshire audiences, the envious world at large is snatching several of them away next summer. So make sure you get along there for that next trip to heaven on Dec 6.
