Omaha gut-rock ramblers Cursive return next month with I Am Gemini, a concept album about the mythological/astrological twins referenced in the title. We’ve already posted one song, “The Sun And Moon.” For a second taste, click the jump and stream the jagged, gnarled math-rock heaviness of “The Cat And Mouse.”

I Am Gemini is out 2/21 on Saddle Creek.
