Hip-hop duo Dead Prez, composed of members Stic.man and M-1, has been entertaining fans since 1996 with a confrontational style of music with lyrics focused on militant social justice. Dead Prez’s debut album, “Let’s Get Free,” catapulted it into the spotlight with singles such as “Police State with Chairman Omali” and “Hip-Hop,” gaining the group attention both musically and politically. A multivolume mix-tape project called “Turn off the Radio” soon followed, and the duo’s music since has been featured everywhere from social documentaries to “The Chappelle Show” without losing any of its progressive bite. Dead Prez performs at Kingdom on Wednesday, Nov. 23, at 7 p.m. $17. kingdomrva.com.
