Inspired by Mississippi-inspired blues guitar, in 1950, Roebuck “Pops” Staples bought his first electric guitar, amp and the tremolo effect that would help define his sound. No stranger to racism, Pops protected his family while they traveled on the road. Those experiences turned into hit songs like “Respect Yourself,” “If You’re Ready (Come Go With Me)” and “Why Am I Treated So Bad,” a favorite of Dr. Martin Luther King. The Staple Singers were inducted into the Rock Hall in 1999.
