The mighty Zepparella is back in town, hosted, once again, at Humbrews, a good venue for this act. What is this act exactly? It’s pretty simple, really. An all-female Led Zeppelin tribute band, focusing on a lot of the power of the erstwhile band’s bombastic sound which has more or less ruled the world of rock since its heyday in the 1970s. If you are one of the band’s many fans, come see what sorcery this quartet can cook up in its honor. 8 p.m. ($30, $25 advance).
