The Brodsky Quartet is in Australia principally for the Sydney Festival. In a coup for the Brisbane Powerhouse, they'll also be doing a Brisbane gig on Saturday night. They'll be playing a program including Beethoven's String Quartet Op 59 No 2 and Gershwin's Lullaby. But to hear them play The Juliet Letters with Elvis Costello, you'll have to go to Sydney (and already have a ticket).
