The 5+2 Brass Ensemble boasts a unique line-up comprising two trumpets, French horn, trombone, bass trombone, double bass and drum kit, and features some of Melbourne's most fascinating jazz and classical musicians including, trumpeter/composer Peter Knight, bass trombone virtuoso Adrian Sherriff, double bassist Anita Hustas, and former Australian Opera principal horn, Geoff Collinson. Together, they produce a sound described in reviews as "lush" and "intriguing".
Their debut album, Invisible Cities and Other Works, traverses terrain ranging from sublimely melodic extended jazz compositions to impressionistic soundscapes rendered in textures unique to 5+2's unusual instrumentation and approach. The album includes an extended suite composed inspired by the dreamscapes conveyed in Italo Calvino's Invisible Cities.
