The second-ever PorchFestFEST took over the Lawn on D in South Boston on Saturday afternoon, bringing local acts and performers from the Berklee School of Music together for a day-long jam session. Attendees of all ages were treated to lawn games, make-your-own-tutus sessions and access to an "ask a teenager" booth. While no porches were involved, performers from the neighborhoods of Dorchester, Roxbury, Jamaica Plain and Mattapan were asked to share in the spirit of Jamaica Plain and Somerville's annual events.
