[5] Felip attended Cagayan de Oro College and studied architecture before his musical career began.
SB19's leader, Sejun (now Pablo), said that the band had begun to grow disheartened after training so long, but receiving little attention.
[4] In April 2021, SB19 became the first Filipino act to be nominated for a Billboard Music Award when they became a contender for the fan-voted category Top Social Artist.
His outfit, a red lace top paired with high-rise pants, drew attention on social media.
He wrote and composed the slow R&B track—a departure from SB19's energetic pop style—about someone walking away from a relationship, with lyrics in Cebuano, Filipino, and English.
The song was written by Felip, who composed the melody, and described by GMA News' Shia Lagarde as having a "more experimental and aggressive sound", influenced by rock and hip-hop, than "Palayo".
[22] Both the song and the music video were inspired by Philippine mythology;[23][24] he used the story of Bulan, Haliya, and the Bakunawa as a metaphor for crab mentality.
[33] On November 8, Felip released his rendition of Never the Strangers’ “Moving Closer” as part of ‘The Classic Cover’ series in celebration of Warner Music Philippines’ 30th anniversary.
One of the producers explained that he was a unanimous pick because “he is from Cagayan De Oro (CDO), and his music resonates with AEGIS on a personal level”.
[35] On December 22, Felip released an unannounced single “Kanako”, which is a departure from his signature rap style, and features a primarily rock sound with lyrics in both Cebuano and English.
[36][37] Ken is a fan of metal and rock bands such as IV of Spades, Slipknot, Korn, Metallica, FM Static, Sleeping with Sirens, and Paramore.
[3][20] Ken's inspirations for "Bulan" included Post Malone, Lay Zhang, One Ok Rock and Jaden Smith.
[38] He was influenced by hip-hop artists such as Al James, Kendrick Lamar, Travis Scott, Post Malone, Kid Cudi, and Lil Uzi Vert in Complex.
[3] He considers his solo work a way to explore genres of music other than his band's P-pop,[20] saying that his songs as Felip are more experimental.
After the release of Complex, HipHopDX Asia's MC Galang wrote that there was "no set precedent" for pop stars in the Philippine music industry successfully crossing over to another genre, like Felip has.
[20] Filipino magazines such as Nylon Manila have highlighted Felip's "experimental" fashion choices, writing that he blends menswear and womenswear together.
[27][43] NME's Tanu I. Raj, after interviewing the band, wrote that "Ken remains the tempered, silent pillar throughout, speaking only when the others prod him to, and only after glancing at them from the corner of his eye.
