Oliver and the band remotely knew each other, as they were part of the same music scene. Oliver used to play bass guitar in small local bands in his late teens, and was offered a place of the lead vocalist in Ian Watkins and Lee Gaze's first band Fleshbind, he loved the offer but he declined as he had to go to university
The band have stated that Oliver was only added to the band so he could go on tour with them as a photographer, for they were impressed by his work. The band asked their management if they could bring Oliver on tour with them in 2000. They were told they couldn't afford to take someone who wasn't part of the band or their crew with them, so Oliver bought a set of turntables and quickly learnt what he needed to play. It is unclear how this occurrence coincides with ex-turntablist DJ Stepzak's departure from the band. As the band themselves worked on the remastered Thefakesoundofprogress, it can be assumed that the notably larger changes in the turntable and sample parts (recorded by Stepzak) compared to the other instruments is due to Oliver's influence on the record. It is likely some samples and scratches added to the remastered edition were recorded by Oliver (Watkins is known to have recorded additional vocals), but this cannot be known for certain.
Jamie is now the Keyboard Player, synthesizer and founding member of the Welsh/American Alternative Rock Band No Devotion who's debut Album is due for release in September 2015.
Oliver is also an aspiring artist and had made quite a successful career before joining Lostprophets. Some of his works have been known to sell for up to £5000 each. Jamie studied fine art at the University of the West of England, Bristol. As an adolescent he used to take photos of small town life in his Welsh village of Cilfynydd, in the community of Pontypridd, and painted them back on canvas. Then, as a student, he took interest in adapting the Tales of Mabinogion, traditional Welsh tales, into modern scenes. Oliver has worked with Ian Watkins on all of Lostprophets' artwork since 2003, possibly before, and he drew the pictures found in the booklet of the album Start Something (also used on covers for the "Burn Burn" single) personally. From 2009, he started to paint again, stating that his new works allowed him to express himself much better as an artist than his older works did. His newer works mostly represent children finding themselves alone in landscapes of war or desolation. Oliver attributes this recurring theme to the fears brought by fatherhood in our current world state. He also mentioned the study of Taoism and meditation helped him develop the new expression technique. Oliver's first showing in America opened in Los Angeles at the Known Gallery, in January 2013, displaying most of his newer works. Oliver also collaborated with the association skate4cancer, painting the piece "Dream, Love, Cure" and selling prints for the charity.
