Chailly and his orchestra began in May 2011 with celebrated concert performances of Mahler 2 and 8 at the prestigious International Mahler Festival in Leipzig. The International Record Review wrote of these performances: "Chailly's conducting has a concentration, attention to detail, expressive range and architectural strength that combine to make this one of the most memorable Mahler performances of the 2011 anniversary year." In April 2012 Riccardo Chailly and his orchestra continued their Mahler performances, presenting Mahler's 4th Symphony with acclaimed soloist Christina Landshamer at the Gewandhaus, Leipzig.
