1. Karen Carpenter, the Carpenters.
What's that you say? Did I hear a snicker out there? Shame on you and go dig out your mom's old LP's and check out this lovely lady who met such an untimely end. Whether it's Rainy Days and Mondays or Superstar, or the honey-dripping Yesterday Once More and Close to You, Karen Carpenter's vocals epitomized the new easy listening style of the early to mid-1970's. She was tailor-made for the diversion of AM and FM radio, maintaining a presence on what would become the "older" frequency, seemingly left behind by rock's progression into experimentation.
2. Christine McVie, Fleetwood Mac.
I'll bet more people identify Stevie Nicks with the band than they do Christine McVie. And that's fine -- it was Nicks and then-boyfriend Lindsey Buckingham who made Fleetwood Mac the commercial success they became in the 1970's and on into the next decade. But McVie was there first, and continued to produce hits. Her voice was quite different from Nicks, and really fit the personality of the songs on which she sang lead vocals. Don't Stop, Little Lies, Everywhere, Hold Me, Over My Head, and You Make Loving Fun are all standards for the band, and for those who listened to Top 40 radio during the Bronze Age of Comics.
3. Alison Moyet, Yazoo.
4. Chrissie Hynde, the Pretenders.
The Pretenders have been a lasting act, first hitting it big in the US in 1980 with the catchy Brass in Pocket. Middle of the Road and Back on the Chain Gang got huge radio play in the mid-'80's as well. Hynde's punky, sometimes bluesy vocals are often sassy -- appropriate for the sound of the band. A side note on Hynde -- although the Pretenders were formed in the UK, she originally hails from Akron, Ohio and was a student at Kent State in 1970 during the infamous Kent State killings.
5. Pat Benatar.
Seriously -- you can't forget the intro. to Heartbreaker, Benatar's breakthrough hit. Although she slipped into video "say what?!" with her crazy dancing performance in Love is a Battlefield I'll forgive her. And despite her diminutive size (she's what, five feet tall?), her voice is impressive.
6. Ann Wilson, Heart
Here's your bonus -- how could I leave the Wilson sisters off the list? Straight On, Dreamboat Annie, Barracuda, Magic Man, Even it Up, and on and on. Rockers, hit makers, and let's face it -- Nancy's held up pretty well over the years. But it has always been Ann's driving, even loud, vocals that symbolize the band's sound. When I think of Heart, it's Ann Wilson that I hear first -- not any trademark musical sound.
