The Lake George Arts project is celebrating 40 years of Jazz at the Lake music festival. For the third year, “Jazz at the Lake” will expand beyond the bounds of Shepard Park into the community and on to the lake itself. Bands will play throughout Lake George Village and, on Sunday, Sept. 15, on a jazz cruise aboard the Lake George Steamboat Company’s Mohican. For a complete schedule, visit lakegeorgearts.org.
