Classical Preview: Musical night where you move Bach and forth

Five hours of non-stop music and you sit where you want, move around, come and go as you please, while the musicians play on. Light Night: Sit Bach and Enjoy is on October 8; it's free and you don't need a ticket. That's one of 19 innovative events taking us to Christmas in the Howard Assembly Room with a potent mix of words and music, and great names in the classics.

Before the curtain goes up on Opera North's opening night of Benjamin Britten's Turn of the Screw, why not join the star of Pinocchio, Victoria Simmonds, and pianist Ian Buckle, in a

short concert of works by Debussy. It's free, but you need a ticket.

This Thursday, hear the hypnotic sounds of the Southbank Gamelan Players, and coming up is Kate Royal, one of our most glamorous young singers, who brings an evening of songs by Schubert, Ravel and Strauss (October 21). Paul Lewis's recent recording of the Beethoven Piano Concertos has been described as "today's number one choice", and he has chosen to play works by Mozart and Beethoven (November 4). Another legend in their own time, the Skampa Quartet, are joined by the singer, Iva Bittova, in an arrangement of the original piano accompaniment to Janacek's Moravian Folk Poetry in Song. The first half is given to the composer's second quartet, Intimate Letters (November 24).

The acoustic is ideal for opera, the chamber group, Music Theatre Wales, staging a new production of Philip Glass's highly disturbing opera, In the Penal Colony. Fictional, but a depiction of barbaric justice that was meted out in such locations (October 28).
