I’m going to go with a North Carolina native (now living in Athens, GA as far as I know) and UNC alum: Eric Bachmann (this won’t shock anyone who is familiar with my username).
His voice evolved quite a bit over time. In his very early work with his first band, Small, with whom he played very briefly in the early-90s (they went on to put out several albums without him), his vocals at the time were very much inspired by J Mascis, and that version of his voice is certainly not what makes him a great singer.
He left Small and focused on the band he’s best known for— Archers of Loaf— throughout most of the 90s. While there was a still a little J Masic influence apparent in his vocals, particularly in his earliest songs with Archers, his vocals became a much more assertive and aggressive baritone. He eventually added a falsetto to his repertoire.
After Archers of Loaf broke up (they’d later get back together nearly 15 years later), Bachmann started his solo project, Crooked Fingers. With Crooked Fingers, his vocals generally evolved into a gentler, yet still assertive and also rugged, baritone. That’s pretty much been his vocal style over the past 25+ years in his work under his Crooked Fingers moniker and in his work that he has released under his own name. He’s also put out some fairly recent music with Archers of Loaf, where his vocals are more aggressive version of that assertive baritone.
Here is a very recent video recorded in the past few months of him performing a solo acoustic version of a Crooked Fingers song that was released in 2003:
