In hip-hop, the East Coast, West Coast and the South all have their distinctive sounds. From the East Coast’s complex lyricism to the South’s slowed-down, chopped-and-screwed style, each area has its own identity and contribution to the genre. So what did the Midwest bring to the table? Hip-hop heads will argue it’s the rapid-fire “chopper” style of Cleveland’s Bone Thugs-N-Harmony or Chicago’s Twista. Include on that list Kansas City’s Tech N9ne, who since the early ‘90s has been delivering a healthy dose of machine-gunfire verses. Jumping to several record companies before starting his Strange Music label in 1999, Tech N9ne, born Aaron Dontez Yates, assumed the role of black sheep in the hip-hop world. His lyrics are no-holds-barred, and he’s even brought on rock vocalists to collaborate, like Korn’s Jonathan Davis, who was featured on 2016’s “Starting To Turn.” Earlier this year, the rapper announced his 2018 “Independent Grind Tour,” a two-month, 40+ city trek across the United States. The tour will feature Dizzy Wright, Futuristic and Krizz Kaliko with a stop in San Antonio at the Aztec Theatre on Tuesday.
