Jeffrey Adam Gutt (born May 2, 1976) is an American singer and songwriter who has been the lead vocalist for Stone Temple Pilots since November 2017.

He first appeared in season 2 (2012) when he drew international acclaim for his heartfelt rendition of Leonard Cohen's "Hallelujah", before being eliminated in the following "Boot Camp" episode.

Innerfaith wrote and performed original songs, ultimately winning the "Blue Water Area Battle of the Bands" in Marysville, Michigan.

In 2012, two early extended plays featuring Gutt on vocals were made downloadable for free through his official site: a three-track 1992–1995 compilation (named Nautical Star by fans for its cover) and a four-track Dragonfly (1997).

Gutt became the lead vocalist for Dry Cell by joining the rock band Beyond Control which consisted of members Danny Hartwell, Judd Gruenbaum, and Brandon Brown.

[6] In 2005 (when Dry Cell went on hiatus), Gutt and his friend, guitarist Gary Pittel, formed Band with No Name (abbreviated as BWNN).

[7] The band also included Aaron Hutchinson (drums), Justin "Antic" Hackman (keyboards), Mike Guy and later Ben Lula (bass).

In late 2015, Rival City Heights toured the Middle East (Jordan,Turkey, Egypt, Lebanon) and India for a series of concerts in association with the Princess Alia Foundation.

[citation needed] On November 16, 2016, Entertainment Tonight reported that Stone Temple Pilots had recruited Gutt to be their new lead singer, replacing Chester Bennington, who had left the band one year earlier.

"[22] A year later, on November 14, 2017, Stone Temple Pilots officially announced Gutt as their new lead singer and played their first concert with him that same night at the Troubadour in Los Angeles.

In an episode broadcast on September 20, 2012, Gutt sang "Hallelujah", a cover of Leonard Cohen, getting unanimous four "yes"es from the judges Simon Cowell, Britney Spears, Demi Lovato and L.A.

[30] Ultimately, Gutt was the runner-up for The X Factor season 3, finishing second place to Alex & Sierra in a razor-thin margin of votes from American viewers.
