Eight Gigs: Mothership

Texas rock trio Mothership shouts “Rock ’n’ roll is here to stay” in the song “City Nights.” It’s not the kind of line you’d expect to hear from a band that formed in 2010, or at least with the kind of sincerity that Mothership has shouting it. That’s because they’re hardcore ’70s lovers: long hair, ripped jeans, mutton chops and all. The kind of songs these guys play is right on par with such amped-up heavy blues-rock bands as ZZ Top, Molly Hatchet and Black Sabbath. 1517 21st Street, http://mothershipusa.com/.
