Check out Amy Grant. She's like the Christian version of Michael Jackson, very popular with Christians (and her music is excellent, too.)
I've been a fan of Amy's since I was very young; my Mom loved her music too, and often played it on the radio. We didn't have many of her albums, but our local Christian radio station would play her songs all the time.
I heard her tell a story once, about what happened when she got her first record contract. She was just 15 years old, and the man who would become her agent called late on a school night to inform her that he wanted to sign her to his label. While they were discussing the details, her father called out, "Its a school night, Amy - hang up the phone!" But she was so determined to be a musician, that she finished that phone call instead...and her father promptly grounded her for it. So she was stuck with only school and home for a short while, and then eventually she started working with producer Brown Bannister's label, then called Myrrh Records. They kept her under contract from 1977 until 2002, when she switched to the Word Records label.
Her most popular album to date is 1991's "Heart in Motion", which saw her cross over from traditional gospel music to a more mainstream sound. Back then, Christian labels were much more territorial, and Amy got a lot of flack for her decision. But the album produced some of her most well-known songs, including "Baby Baby", "Every Heartbeat", "That's What Love is For", and "I Will Remember You". She would release four more albums (including two Christmas-themed ones), before doing a 2002 gospel compilation called "Legacy... Hymns and Faith". Her last completely original album so far, "Tennessee Christmas", was released in 2016.
Aside from her music, Amy's personal life has suffered a few setbacks, some of them rather public. She was married to her first husband, fellow musician Gary Chapman, from 1982 to 1999; they had three kids together (Matthew, Sarah, and Gloria). About a year later, she married country singer Vince Gill; they have one child (Corrina). Regarding her marriages, Amy clarified in an interview for CCM Magazine:
"I didn't get a divorce because 'I had a great marriage and then along came Vince Gill.' Gary and I had a rocky road from day one. I think what was so hard - and this is (what) one of our counselors said - sometimes an innocent party can come into a situation, and they're like a big spotlight. What they do is reveal, by comparison, the painful dynamics that are already in existence."
In June 2020, Amy had an open-heart surgery to repair partial anomalous pulmonary venous return (PAPVR), a congenital heart condition. In 2022, she was recognized as a recipient of the Kennedy Center Honors, alongside fellow honorees U2, George Clooney, Gladys Knight, and Pulitzer Prize-winning composer and conductor Tania Leon. During the course of her career, Amy has also won 6 Grammys, and 22 Dove Awards (the Christian variety). Not bad overall, for a woman of 63 years who's still determined to keep going. In 2023, she re-released her 1988 effort "Lead Me On", as a 2-CD set in celebration of the live tour's 34th anniversary.
Lastly, a small personal note - I actually got to see Amy perform, at a Christmas show she was doing with Michael W. Smith in 2016. They also shared the stage with surprise guest Jordan Smith (no relation). I loved the show, and even tried to meet Amy backstage...but the security guard stopped me, literally leaving me freezing in the cold for some time...not a good memory. But otherwise, I really enjoyed the concert, and when I can afford to go again, I plan to.
