London's Barbican has invited two more groups to join its family of Associate Ensembles. Period-instrument group The Academy of Ancient Music and Cambridge-based Britten Sinfonia will both become a regular part of Barbican seasons, along with the London Symphony and BBC Symphony orchestras (resident ensemble and associate orchestra respectively).

The AAM’s debut Barbican season will include Bach’s St John Passion, with soloists including James Gilchrist and Sarah Connolly, and Christopher Hogwood conducting the rarely-performed Handel opera Imeneo, with soloists Lucy Crowe, David Daniels, Matthew Rose and Stephan Loges. The Britten Sinfonia, meanwhile, will mark its 20th anniversary in October with concerts and free events featuring music from Byrd to Nico Muhly, including a birthday tribute by James MacMillan.

The announcement was made as part of the unveiling of the Barbican’s 2012-13 season, during which it will welcome the Los Angeles Philharmonic and its music director Gustavo Dudamel to an International Associate residency at the Barbican. The LA Philharmonic joins four other ensembles with International Associate status at the Barbican – the Gewandhaus Orchestra Leipzig, Jazz at Lincoln Center Orchestra, New York Philharmonic and Royal Concertgebouw Orchestra of Amsterdam.

The season also sees violinst Leonidas Kavakos become the UBS Soundscapes: LSO Artist Portrait musician, Mark-Anthony Turnage the subject of an LSO Composer Focus, and features a 'Total Immersion' weekend from the BBC Symphony Orchestra celebrating the 60th birthday of the composer Oliver Knussen.

Other musicians who will grace the Barbican stage from autumn onwards include sopranos Renée Fleming and Dawn Upshaw, tenor Juan Diego Flórez, violoinst Alina Ibragimova, pianists Elisabeth Leonskaja and Maria João Pires, and conductor Bernard Haitink.
