The annual concert, planned for Dec. 7 at Trackside Teen Center, supports the Wilton food pantry and the Connecticut Food Bank. Over the past four years, Wilton Rocks for Food has donated more than $150,000 to The Connecticut Food Bank and more than $130,000 to Wilton’s food pantry.

Begun in 2015 when $26,000 was raised, last year’s event featured 35 musicians and a silent auction with 100 items. A total of $125,000 was raised. Concert organizers hope to raise $150,000 at this year’s concert, with all proceeds going to charity.
