Photographer Kelly Davidson (right) celebrated the fifth installment of her “Rock ’n’ Roll Parents” series with a party at Q Division Studios in Somerville on Friday night. The new batch of images features musicians such as Chris Colbourn of Buffalo Tom, Will Dailey, and Caroline Toth of Apple Betty. Fans of Davidson who came out for the event included Gonzalo Plaza (left) of New Hampshire, who was kind enough to bring flowers. Davidson photographed Plaza’s wedding at Walt Disney World in November. Weeks later, Davidson had her own wedding at the Center for Arts at the Armory in Somerville.
