Guitar Ray was George Raymond Washington. He released around 6 45s as Guitar Ray (Shagg, Invicta and 4 on Hot Line all New Orleans labels) and 2 as Ray(mond) Washington in 1959 and 1961.
To be perfectly honest apart from 'You're Gonna Wreck My Life' which is a superb crossover tune, most of his material is not particularly suited to this site as much of it is blues, but I've linked to as many as I could find.
