During the second half of the decade major changes were made to the conductorship of the orchestra . In 2006 Daniel Harding joined Michael Tilson Thomas as principal guest , and the following year Davis retired as chief conductor and was appointed president of the orchestra , its first since the death of Bernstein in 1990 . Davis was succeeded as chief conductor by Valery Gergiev . In Gergiev 's first season in charge a complete cycle of Mahler Symphonies was given , with the Barbican Hall sold out for every concert . In 2009 Davis and the LSO celebrated 50 years of working together . In the same year the LSO took over from the Berlin Philharmonic as the resident orchestra at the Aix-en-Provence Festival , adding to a roster of international residences at venues including the Lincoln Center in New York , the Salle Pleyel in Paris and the Daytona Beach International Festival in Florida . In 2010 the LSO visited Poland and Abu Dhabi for the first time and made its first return to India since the 1964 world tour .
