Cleveland gangsta-rap crew Bone Thugs-N-Harmony is an example of an act that has persisted in its own musical vision and kept the fickle hip-hop industry’s whims far in the background. Bone Thugs will be performing with all five original members as they roll through Saytown on their 20th Anniversary tour. Slated to release their ninth studio album sometime this year, a follow up to 2010’s far-ranging Uni5: The World’s Enemy, Bone Thugs’ showmanship and sense of purpose has only been emboldened through the years and pitfalls. In live performances, you get a magnified sense of their individual skills with melody, harmony, and hypnotic Chopper-style flows. For fans of hip-hop old and young, this is a chance to see masters of the craft at work in the surprising power of their third or fourth wind. $27.50-$30, 7pm, Backstage Live, 1305 E Houston, (210) 698-2856, backstagelivesa.com.
