ONE​-​OFFs & ONE​-​UPMANSHIPs is an absorbing piece of hip-hop outsider art that laces the staunchly working-class world view of Brooklyn and Long Island–raised MC, artist and bootleg toy creator Tone Tank with copious deep rap references and off-kilter witticisms. Unbridled lyrical creativity pulses through the 2015 project: The scuzzy lolling funk of “Cop/Boost” presents Tone and guest Serengeti weaving together the plots of two obscure ’80s James Woods flicks; “Big Shot In My Own House” channels Ultramagnetic MCs–style braggadocio; and the socio-economic statement “Rich Kids” includes Tone addressing the old adage about putting the cart in front of the horse by quipping, “That ain’t gonna work unless, of course, the horse can moonwalk.” A conceptually multifarious hip-hop gem.
