Ben joined Libera in early 2006 shortly after his 10th birthday. Since then, he has been featured as a main member of Libera and appears alongside soloists Tom Cully, Michael Horncastle, etc. In February 2007, Ben got his very first solo, Lacrymosa. He also sang with Joshua Madine and Tom Cully in one of Libera's most famous songs, Going Home in the Angel Voices-Libera in Concert DVD.
He also sings solos in The Lamb and Jerusalem on the album New Dawn.
On Libera's most recent tour to the Philippines (October 2009) Ben sang the solo part on "Bayan Ko", a patriotic Philippine song.
Ben is credited 5 times on the new album, Peace, contributing both solos and supporting duets. He has transitioned smoothly into being one of the group's main soloists.
He also reprises his role as the soloist in "Lacrymosa", giving it a new depth of tone.
One of his best solos is in the song and music video "Time" from 2010
