"63" and "19" received mostly positive reviews from critics. "Vice" described "19" and "63" as "taking the discursive and funny work he was doing with Das Racist and stripping it of any sense of structure or formula, but also work[ing] to free him from the label of 'Dude in Das Racist.'" "Pitchfork" also praised the mixtapes, calling them "organically avant-garde", giving "19" a score of 7.9 out of 10 and "63" a score of 7.6 out of 10. Afropunk lauded the albums as "challenging, vibrant, and sometimes brilliant." Contactmusic.com named "63" one of the ten best albums of 2013.
