He was hospitalized in April for a few days after suffering from dehydration related to the disease. In May he said in a Facebook post that he was in hospice care at his home.King had a deep, resonant singing voice and, despite having what he called "stupid fingers," an immediately-recognizable guitar sound.His unique style of trilling the strings with a fluttering left-hand vibrato, which he called it "the butterfly," helped shape early rock.
