Rich Homie Quan, an Atlanta rapper who played a role in the city’s thriving hip-hop scene in the 2010s, has died at a hospital in Atlanta. He was 34.

His death was confirmed on Thursday by the Fulton County Medical Examiner’s Office, which did not provide a cause.

A melodic rapper who broke out in one of the country’s most fertile rap scenes over a decade ago, Rich Homie Quan has more recently become a character in the sprawling gang conspiracy trial in Georgia centered around Young Thug, the Atlanta superstar.

Quan’s early career was closely tied to that of Young Thug; the two were members of Rich Gang, a group assembled by Bryan Williams (a.k.a. Birdman), one of the founders of the label Cash Money.

Their slow-rolling debut single from 2014, “Lifestyle,” was a Hot 100 hit and has been certified platinum. The pair later fell out over what Quan said were issues around ego and money, and parts of their feud have spilled over into testimony at the trial.

In 2013, Quan broke out solo with “Type of Way,” a song about ambition and romance that the Michigan State football team adopted as an anthem. In The New York Times, the critic Jon Caramanica wrote about the track, proclaiming Quan part of a new generation of rappers “who deliver lines with melody and heart, like singers on the verge of a breakdown.”
