Kellin Quinn is an American singer, songwriter, and musician best known as the lead vocalist and keyboardist of the post-hardcore band Sleeping with Sirens.
He joined the band in 2009 and has since fronted eight studio albums while building a parallel career through solo projects, high-profile collaborations, and a clothing business.
Who is Kellin Quinn?
Kellin Quinn Bostwick is an American rock singer from Medford, Oregon.
He performs under the name Kellin Quinn and leads Sleeping with Sirens, one of the most recognized bands in the post-hardcore and pop-punk scene of the last two decades.
Alternative Press has called him one of the most recognizable voices in the scene, and his leggero tenor range sets him apart in a genre dominated by heavier vocal approaches.
That range lets him shift between clean, melodic passages and aggressive delivery within a single song.
Beyond Sleeping with Sirens, Quinn has logged collaborations with artists including Pierce the Veil, Machine Gun Kelly, and Travis Barker.
He also co-wrote a track for the Sonic Frontiers video game soundtrack in 2022. In 2025, he released A Collection of Greetings, his debut studio album under the solo project Haunted Mouths.
Quinn also owns the clothing line Anthem Made and launched Dreamer Development Group in 2019, a support network for emerging artists.
Early Life of Kellin Quinn

From a young age, he was drawn to music, and he has shared that he knew the words to the Beach Boys’ “Kokomo” when he was four years old.
He got involved in his local music scene as a teenager and began playing in bands while still in high school.
His early musical roots in Oregon shaped a melodic sensibility that stayed with him through his career in post-hardcore.
Quinn moved to Florida in 2009 to join Sleeping with Sirens, a decision that shifted the trajectory of his career.
Before that move, he had spent years performing in local bands and developing his vocal approach through live performance rather than formal training.

Kellin Quinn Musical Style and Influences
Quinn’s vocal style draws heavily from melodic rock and pop-punk traditions, layered over the heavier post-hardcore sound that Sleeping with Sirens built their early reputation on.
He cites the Beach Boys as an early influence, and that melodic instinct runs through the band’s pop-leaning periods just as clearly as through their heavier work.
His collaborations reflect a wide taste: “King for a Day” with Pierce the Veil sits in the post-hardcore space, while “Love Race” with Machine Gun Kelly and Travis Barker moves into pop-punk territory.
His Haunted Mouths solo project, launched in 2025, pulls toward indie pop and more acoustic arrangements.

Kellin Quinn Career
Kellin Quinn’s professional music career began in Medford, Oregon, and grew through a series of band memberships before landing him in Sleeping with Sirens in 2009.
Since then, he has fronted the band through eight studio albums while expanding his reach through solo work, acting, and business ventures.
Early Career (2005–2009)
Quinn played in the band Closer 2 Closure from 2005 to 2008, alongside guitarist and songwriter Titus Lockard.
The band released music to Myspace during that period, which was the dominant platform for unsigned rock acts at the time.
He also served as vocalist for the Michigan band For All We Know during this period. In 2008, Quinn auditioned for the vocalist position in Dance Gavin Dance but did not make the final cut.
In 2009, he moved from Oregon to Florida to join the newly forming Sleeping with Sirens.
That band came together around the same time through members Nick Trombino and Brian Calzini, and Quinn stepped in as lead vocalist, quickly becoming the defining voice of the group.
Sleeping with Sirens Breakthrough (2010–2015)
Sleeping with Sirens released their debut studio album, With Ears to See and Eyes to Hear, in 2010 through Rise Records.
The album sold 25,000 copies and reached number 7 on the US Heatseekers chart. It introduced Quinn’s high tenor range to the post-hardcore audience and established the band’s emotional, guitar-driven sound.
Their second album, Let’s Cheers to This, followed in 2011 and reached number 5 on the US Hard Rock chart and cracked the top 20 on the US Indie chart.
The single “If I’m James Dean, You’re Audrey Hepburn” became one of the band’s signature tracks.
Feel (2013) took the band to their highest chart positions to that point, reaching number 2 on the US Indie and US Hard Rock charts and number 3 on the Billboard 200.
Madness (2015), released through Epitaph Records, followed and kept the band at the center of the post-hardcore conversation.
Quinn also contributed to Pierce the Veil’s single “King for a Day” in 2012. The track achieved gold certification in 2014 and platinum certification in January 2020.
Continued Output and Solo Work (2017–Present)
Sleeping with Sirens released Gossip in 2017, How It Feels to Be Lost in 2019, and Complete Collapse in 2022 through Sumerian Records.
In 2026, the band released An Ending in Itself on June 12, returning to Rise Records and working with producer Will Yip.
Quinn’s most widely recognized collaboration outside the band is “Love Race” with Machine Gun Kelly, released April 29, 2021, and later included on Kelly’s sixth studio album Mainstream Sellout (2022) in collaboration with Travis Barker.
In 2022, Quinn co-wrote a track with the SEGA Sound Team for the Sonic Frontiers video game soundtrack, bringing his songwriting into an entirely new medium.
He also appeared in three episodes of the American musical drama series Paradise City.
In 2025, Quinn launched the Haunted Mouths solo project and released its debut studio album, A Collection of Greetings.
The project gave him a separate creative space from Sleeping with Sirens with a sound that leaned toward indie pop.
