Things to do around Boston this weekend and beyond - THE BOSTON GLOBE
LOWELL FOLK FESTIVAL A typically formidable roster of artists is on offer at this year’s edition of the all-free mid-summer festival. On my must-see list: the country/rockabilly sounds of former BR5-49er Chuck Mead, some sacred steel courtesy of Fran Grace, funk pioneer Fred Thomas, western swing trio Hot Club of Cowtown, kora griot Sona Jobarteh, Springfield Exit’s bluegrass/acoustic country mix, and the Haitian roots music of Lakou Mizik. July 28, 6:15 p.m.; July 29-30, noon. Free. Various stages, downtown Lowell. 978-275-1764, www.
