After the success of his previous two projects, Logic released his third mixtape Young Sinatra: Undeniable on April 30, 2012. The mixtape is notable for Logic addressing various personal topics, including his future, his father’s drug use, his expulsion from school, and his mother getting stabbed. Speaking about the mixtape, Logic said, “Fans tend to think that if you fall in love with an artist because he makes this kind of sound [but if he gets] bigger and he grows and [his sound changes, people also think he changes]. But with me, I created all types of sounds from the get go, so you can never say I’m changing.” He commented on the musical aspects of the mixtape, stating, “There’s stuff on there for the motherf***ers that don’t pay attention to lyrics and just want to have fun, but every line is constructed with such depth that the real lyricists and nitpickers have something to listen to.” After the release of Young Sinatra: Undeniable, Logic completed his first national headlining tour, the Visionary Music Group Tour.
