Minneapolis rapper the Lioness may be the city’s premier North Side lyrist, as demonstrated on her truly special album from last year, Growing Pains. The LP followed a run of mixtapes from the rapper and McNally Smith grad — The Most Anticipated, Lost Tapes, and Queen — that began in 2011. At this point, she’s one of local rap’s best-kept secrets. Growing Pains is a powerful, introspective album that examines, among other things, race in America, making it a rich document for the Black Lives Matter era. At the same time, the MC born Shaiwna Adams is a deeply purposeful storyteller of various personal struggles (e.g., overthinking and over-drinking). Last year, she told City Pages she aspires to be “a voice and an advocate for women — women of hip-hop and women of color especially.” Tonight’s Icehouse gig is a special “unplugged” performance with guests including Myke Shevy, aka MMYYKK of ZULUZULUU.
