BONUS TRACK!! Last week, musician Rebecca Rego dropped by WBEZ’s Morning Shift to talk about her band, and about quitting her “day job” (which would actually be a night job, given that she was a bartender) to make music her full-time commitment. She stuck around to play an extra bonus track, just for YOU. It’s a new song of hers, “Sorry Business.” Rego performs tonight at Township in Chicago.
