Guest List: Ty Dolla $ign

As a singer, songwriter and producer, Ty Dolla $ign understands his collaborators' strengths and draws them out, to great effect. He enhances Lupe Fiasco's attention to detail, providing tonal colour on the seesawing "Next to It". On "2morrow (We Ain't Worried)" he gives Dom Kennedy's wave-lapping cut a soothing chorus. And his feature on the loping groove "Toot It and Boot It", which Ty also produced, exemplifies his easygoing pop ear.
