The Grand Slambovians play what lead singer and songwriter Joziah Longo recently described as a “country prison music meets British Invasion type of thing.” Once dubbed “the hillbilly Pink Floyd,” their eccentric and highly entertaining tunes are sure to leave you guessing, if not dancing in the aisles of One Longfellow Square (181 State St., Portland) at 8 p.m. Tix: $23 (all ages). 761-1757. onelongfellowsquare.com.
