Tonight 8pm at the Town Hall, the Australian Chamber Orchestra is performing its ‘Revellers’ concert as part of its 2006 concert series. The evening’s pieces will include ‘Birthday Tango’ by Smalley, a world premiere commissioned by Barbara Blackman. They will also be playing Piazolla’s ‘Contrabajissimo’ and ‘Oblivion.’ (Oh, and some other stuff like Dvorak’s Serenade for Strings in E major Op. 22).
