When she was in high school, my mom didn't like Elvis and those guys. She was a Chet Baker fan.
Actually, I've not only bought jazz records for my mom, I've taken her to jazz shows, including Abbey Lincoln and Bud Shank.
Wow.
My own mom didn't like Elvis or Buddy Holly or Fats Domino or any of those fifties rockers either. She also didn't (and doesn't) like jazz, classical, country, or any other type of music. Doesn't like movies either.
