"Serotonin and Guy Cooper were amazing in helping us secure us a record deal & distribution in Japan. Guy mixed our debut ‘Bin Night Anthems’ album & helped create a great sounding international album and film-clip package including press photos, bios and other media. We signed with Serotonin publishing and through Guys management & planning we were distributed into Japan and have sold copies of our album all across the world. Guy and Serotonin helped build The Combovers into an international band and helped us get a spot on the 2006 Big Day Out Festival. We continue to sell copies of both our CD’s today through Serotonin and Guy is continually finding sync and licensing opportunities for all of our songs."

"Guy has been instrumental in helping us to complete our 2nd studio album, his dedicated production and mixing has given us an amazing sounding international album. Serotonin has also created 4 film-clips, a documentary and feature length DVD, along with tour videos and live gig videos. His management and publishing has helped us to create a massive package for the new album which is currently being shopped internationally by Serotonin. Guy has also secured a showcase gig for us in Japan this year in September timed up with a tour of Japan following a spot playing at the 2009 Big Day Out. Serotonin has distributed our CD online and has managed to recoup the printing costs through online sales even before the album is released to the public. Guy has helped create a theme for our album including stage props and lighting and also come on tour and played keys and percussion for us. His knowledge of production and great collection of vintage and modern equipment has developed an epic and original sound for our album."

"Guy has been a pivotal member of the Transport team over the past 7 years, recording and producing the first 2 eps along with producing and mixing several extra singles along the way. He has been a good friend and a true fan of the band, always providing help wherever he can, including helping Transport get a spot on the 2006 Big Day Out. Serotonin has filmed numerous gigs for Transport and has helped created a media presence for Transport online with these videos and more."
