This ten-song mixtape brings together Compton chart-topper YG with Sacramento counterpart Mozzy, the two California rappers playing off each other's strengths on tracks that stay mainly in a high gear. Kommunity Service is front-loaded with its most immediate tracks, hitting the ground running with "Gangsta," a smart and steely revisitation of the instrumental for 50 Cent's 2002 hit "Wanksta." Mozzy and YG use the familiar beat as a launchpad for new intensity, updating the understated cool of the original with an exhilarating, in-your-face delivery. G Herbo guests on the sinister bounce of "Dangerous," and "Bompton to Oak Park" is quintessential West Coast rap, matching tough and sun-dazed flows from the rappers with an instrumental made up of rubbery synth-funk bass lines and speaker-rattling drums. Things slow down with the pop-minded "Vibe with You," but ramp back up with the Tyga-featuring banger "Took It Up" and the relentless push of "First 48." Although Kommunity Service is short, it still shows versatility by approaching various styles track to track. After the string of harder songs that open the album, YG and Mozzy get into reflective lyrics over melancholic piano loops on "Bite Down," and detailed, atmospheric trap production on the unexpectedly catchy "Drop a Location," featuring a sticky sung hook from A Boogie wit da Hoodie. ~ Fred Thomas, Rovi
