Ansbacher, who recently became the Moscow Symphony's principal guest conductor, said in a press release, "the history and setting of the Hatch Shell make it a unique outdoor venue for classical music."
Other performers, in addition to the BLO, include the Longwood Symphony Orchestra, the Greenwood Music Camp Orchestra and soloists from NPR's From The Top.
"We are extrememly excited about undertaking what we hope will become a new summer-time tradition for the residents of Boston," said Ansbacher.
Ansbacher founded Boston Landmarks Ochestra in 2001 to give free performances celebrating historical, geographical and architectural settings. The Landmarks Festival at the Shell begins on July 11 with Beethoven's Ninth and Haydn's "London" Symphonies; the series continues through September 5.
