Fred Seibert only has a career as a rock record producer.
Freed first started playing the music in 1951, and by 1953 the phrase "rock and roll" was becoming used much more widely to market the music beyond its initial black audience
 His more insistent, driving rhythms, hard-edged electric guitar sound, African rhythms, and signature clave beat (a simple, five-accent rhythm), have remained cornerstones of rock and pop
