Waltham Land Trust hosted its 22nd Annual Green Space Blues Jam on Friday, May 15. Dozens of supporters gathered at the historic Robert Treat Paine Estate to bid on auction items, sample charcuterie and enjoy live music by blues vocalist Michelle “Evil Gal” Willson and keyboardist Shinichi Otsu.

The funds will support green infrastructure projects suggested by the Charles River Watershed Association for the Lakeview Preserve on Hardy Pond. These improvements will help treat stormwater before it flows into Waltham’s only great pond.
