Despite her commercial success, she is credited with being a pioneer within the Singaporean DIY and independent musician community, having founded two music-based companies in addition to her own artistic pursuits since 2002.
After parting ways with Japanese record label S2S in 2011, Bevlyn returned to her independent status focused efforts on The Storyteller Wave, the music production and consultancy company she founded in 2013.
Khoo also recorded the theme songs to two Mediacorp TV series: "Cinderella " 灰姑娘 for An Enchanted Life 钻石情缘 in 2006 and "Keep Warm" (保温) for Little Nynoya in 2008.
Khoo performed publicly for the first time as an independent artist in August 2008 at the NUS UCC Theater Hall for the launch of her EP Lonely Afternoon.
[6] Khoo signed a three-album contract with the Japanese independent record label S2S from November 2008 to 2011 which she released the albums, You Are My Angel, Bistro Affair and Feel About You.
In an interview with The Straits Times, Khoo cited creative differences as the reason for the separation, saying "I didn't want to end up with people thinking I sing a lot of covers and that's it.
Bevlyn's first record as a solo artist was Lonely Afternoon, an EP consisting of 5 originals and one gypsy jazz cover of Edith Piaf's "La Vie en Rose" that was released in February 2008.
Moshin Magazine reviewed a live performance of the song, saying "Articulating the verses with fluent Mandarin, Bevlyn easily transitioned into perfectly enunciated English.
GogoYoko says of You Are My Angel, "The most interesting thing about this album is the charm and spirit that Bevlyn manages to inject into long-standing and endlessly covered songs.
[7] In an interview with Music Weekly, Bevlyn explained the album's concept: "I realised that the majority of my songs are usually inspired by the people I know in my life, as opposed to 'fiction-writing'.
Today Online's Christopher Toh gave the record a 3.5 / 5 rating, and said "(Khoo's) emotive vocal delivery works wonderfully on ballads such as The Letter That Never Came.
"[5] Power of Pop observed that Khoo was back in her element as an indie songwriter, and said "(The People I've Known) demonstrates Bevlyn's astute understanding of the soft rock dynamics of the Seventies (which forms the core of Mando-pop).
