Before appearing on
American Idol, Tongi released a single, "Dreams", which he wrote for his sister's wedding in 2020. Other pre-
Idol singles included a cover of
ABBA's "
The Winner Takes It All" and another original single, "Gone". A few days prior to
Idols season finale, Tongi released the single "I'll Be Seeing You". The song reached No. 3 on
Billboards Digital Song Sales and No. 1 on Rock Digital Song Sales, from 11,000 downloads. Tongi credits Hawaii-born singer
Jack Johnson for mentoring him and helping him navigate the music industry. He also credits his family with keeping him grounded in the face of fame. Tongi says the biggest lesson he has learned since winning the competition is to "Be yourself. Don’t let people push you or try to mold you into another person." In a May 2025 interview with
People, Tongi revealed that he had managed to lose weight while working with a personal trainer. "We have a workout session maybe around 11, come back [home], and we go to an ice bath or sauna... or whatever it is. And then we come back, shower and go on a walk. And I've lost 115 lbs. It feels amazing. I feel great."
Post-Idol highlights Shortly after winning
Idol, Tongi embarked on a tour that saw him reunite with fellow contestant Oliver Steele, who finished in the Top 8 and with whom Tongi formed a special bond during the competition. During the tour, while both Tongi and Steele were on Oahu, a local guitar maker gifted the duo custom made, matching ukuleles to symbolize their friendship. On July 1, 2023, at a concert at the
Turtle Bay Resort, Tongi surprised the audience by inviting Roman De Peralta from Kolohe Kai to join him on stage to perform "Cool Down", the same song he showcased on
Idol. The concert was their first time performing the song together. De Peralta said afterward, "He's coming home after an epic win, and I texted him, are you going to jam 'Cool Down' tomorrow? And he said yeah, and I said, ‘Can I join?’ and he was really stoked. I am honored to be here." On July 10, 2023, Tongi sang the national anthem at the
2023 Home Run Derby, but forgot to remove the baseball cap he was wearing before he sang. Tongi apologized on social media, attributing the faux pas to being nervous performing in front of such a large crowd. On August 12, 2023, Tongi released an Instagram video honoring the victims of the
2023 Maui wildfires. Encouraging his fans to donate, and expressing his love and support for the people of Maui, he sang a cover of
Israel Kamakawiwo'ole's "Starting All Over Again". On August 25, 2023, Tongi released a studio version of his duet with James Blunt of Blunt's song "Monsters". Tongi wrote on social media, "From covering it on TikTok 3 years ago to singing it in my audition on @americanidol, to performing it at the Idol finale with @jamesblunt , “Monsters” means so much to me." In 2025, Tongi recorded a new version of the song "Hawaiian Roller Coaster Ride" for the live action film
Lilo & Stitch. Tongi released the song on May 9 and returned to the
Idol stage on May 12 to perform the song. ==Discography==
