Cursive’s latest album, I Am Gemini, twists an eons-old mythological tale of twin brothers into an epic modern struggle between good and evil. Gemini, which is the Omaha indie-rock band's seventh LP – and first since 2009's complicated Mama, I'm Swollen, which dealt with adulthood, sex, and mommy issues -- toys with issues of doubt, betrayal, and other dramatic emotional revelations, all of which continue to define a group that has never shied away from taking themselves too seriously. It’s also a start-to-finish narrative not heard on a Cursive album since 2000's relationship-in-turmoil document Domestica. And it’s big. Like, bigger-than-your-typical-rock-record big. Frontman Tim Kasher has compared I Am Gemini to a theatrical musical, and it's easy to imagine the story playing on an Off-Broadway stage someday. Cursive’s latest, and equally ambitious, tour hopscotches across the country before heading to Europe. It stops at the Grog Shop this week. – Rachel Hoskins
