He def. was an inf. on rock, along with some other country stars, but it is has always been convenient by whites to leave out blues musicians who really had the major infl. of the time.
From Son House's Delta blues in the 20's to Muddy's Urban blues of Chicago, to Big Mama Thorton's Hound Dog, to Little Richard in the 50's, blacks were widely ignored as the inf. of Rock until white Brits arrived in the states, such as the Stones, to re-introduce black Amer. music to white Amer. audiences.
