Already home to some of Hip Hop’s badass-est lyricists [Common, Lupe, ‘Ye], Chicago is once again shaping the musical fostering of another young MC.

Primed to join that elite assemblage, Towkio is in his final promotional stretches of the long-awaited .Wav Theory release. Already dropping the Donnie Trumpet assisted “Free Your Mind” and Vic Mensa collaboration “Involved,” he calls on the rest of his Windy City family for “Heaven Only Knows,” an electro-euphony of dope proportions.

Avondale’s own lets loose and delivers a red-hot flow and then things really get fun. Chance The Rapper checks in with his own fiery verse and songstress Eryn Allen Kane lends her silvery pipes to the mix, all while young producer Lido provides the chill-inducing backing that sees John Legend’s gospel-lite “Heaven” fused with the jazzy-pop stylings this crew is known for.

Just take Chance’s word for it, this may already be the “hottest tape of 20-15.” Look for .Wav Theory out April 28th!
