Singer-songwriter Jeff Hanson was found dead in his St. Paul, Minnesota apartment Friday, the Minneapolis-St. Paul Star Tribune has reported.
It was unclear exactly what caused Hanson's death, but he apparently died from a fall or other accident in the apartment, which has concrete floors, his sister Sara Hanson told the paper.
The 31-year-old musician had been climbing a steady rise to fame with the help of the independent record label, Kill Rock Stars, for which Hanson released three albums, including last year's critically acclaimed "Madam Owl."
Hanson was born in Milwaukee, Wisconsin and began playing guitar when he was just 4 years old. He formed his first band at age 13, and was signed to Kill Rock Stars six years ago.
"Jeff Hanson was an amazing artist, a riotously funny person, and a good friend," the label said in a statement posted on their Web site. "Everyone at Kill Rock Stars feels that we were privileged to put out his records. We will miss him tremendously.
In a radio segment about his last album, NPR called his voice, "one of the most incredible and truly unique voices you'll ever hear."
Funeral arrangements have not yet been announced.
