Battery Steele.

Sunday, June 10

While the straights are munching fried dough and ogling watercolors down at the Old Port Festival, the freaks will be rockin’ to the sounds of the Portland underground (Battery Steele, TheWorst, Acadia and many more) at the 7th annual Mathew’s Rooftop Old Port Festival at Mathew’s Pub (133 Free St., Portland) from noon to 10 p.m. (Fest begins with a daylong bash on June 9.) Cheap cover (21+). 253-1812.
