Jawhar Glass (born January 18, 1980),[1] better known by his stage name Illogic, is an American indie hip hop artist from Columbus, Ohio.

[2] He has collaborated with many artists—particularly Blueprint, who has produced three of his albums,[3] but also Aesop Rock, Vast Aire, Eyedea, Copywrite, Slug, and other MCs.

[6] He released his first four albums with Weightless Recordings which established himself as a forerunner of the indie rap boom.

[7] Illogic then moved to the Dove Ink label which he ran with his friend Eyamme until his return to Weightless Recordings in 2009 for Diabolical Fun accompanied by Ill Poetic.

Speaking on the collaboration, Illogic said, "We have worked hard to really try to find our own identity as a duo and not to try recreate what I've done with other producers and what he has done with other artists."
