Just two weeks after capturing hearts across America and finishing as runner-up on Season 23 of American Idol, 18-year-old John Foster has wasted no time reminding fans why he was a fan favorite from day one. And this time, he’s not on a glitzy Hollywood stage — he’s back home, grounded in the music and faith that shaped him.
On May 31, 2025, the Louisiana native released his first official music video since Idol — a one-take, stripped-down rendition of “Amazing Grace” filmed in collaboration with Fable House. With nothing but his voice, guitar, and the southern spirit that defines him, Foster delivered a performance that felt more like a prayer than a production.
“I thought it fitting that my first post-Idol music video be ‘Amazing Grace,’ because it’s His Grace that’s brought me this far,” Foster shared. “Every lyric, including the Cajun French chorus, is a thank-you to God.”
A Gospel Favorite — With Louisiana Soul
Foster’s fans will recognize “Amazing Grace” as one of the emotional high points of his American Idol run. He first stunned viewers with the classic hymn during his hometown visit, performing part of it in Cajun French on the steps of the Louisiana State Capitol — a tribute to his heritage that resonated deeply with his supporters.
Now, hearing the full version in a dedicated music video, fans are falling in love all over again.
“John always keep this sweet humble spirit that you have,” one fan commented.
Another wrote, “You have touched the hearts of millions with your beautiful voice. How sweet the sound, indeed.”
The video racked up over 10,000 likes in its first 24 hours, with fans praising not just his vocals, but his authenticity and heart. The Cajun French verses added a layer of cultural richness that reminded many of the soul of Louisiana itself — proud, passionate, and full of grace.
A Rising Star with Deep Roots
Just days before the “Amazing Grace” video dropped, Foster shared another special moment: a collaboration with Louisiana music legend Wayne Toups at the Cajun Country Memorial Day Festival.
Posting a photo from the event, Foster wrote:
“I’m a country musician down to my bones, but there are many genres and musicians that contribute to my unique sound. One of them is this gentleman, Wayne Toups, a legend in Louisiana music.”
Together, the pair performed “Mathilda,” blending zydeco and country in a show of musical unity that left the crowd roaring. Toups, a Grammy winner known for his high-octane Cajun-rock fusion, later posted, “We even had John Foster hit the stage with me — pure Louisiana magic! It was one for the books!”
More Music on the Way — and the Opry Up Next
While the video for “Amazing Grace” may have been his first official post-Idol release, Foster had already begun sharing original music. On the eve of the show’s finale, he dropped his debut single, “Tell That Angel I Love Her,” under the 19 Recordings label — a soulful country ballad showcasing his songwriting chops and signature vocal grit.
And now, the next milestone awaits: John Foster is set to make his Grand Ole Opry debut on June 7, a moment he once only dreamed of.
“Stay tuned everyone,” he teased. “I’m working hard to get some great things headed your way.”
At just 18, John Foster is proving that he’s not just chasing a moment — he’s building a legacy. With every lyric, every heartfelt performance, and every humble thank-you, he’s writing the next chapter of a story that’s only just beginning.
