The story of two outsiders and obsessives whose collision prompted an evangelistic alliance on the furthest frontiers of underground music.

Steve Davis first met Kavus Torabi - guitarist with Gong, Guapo, Cardiacs and Knifeworld - in the mid-2000's at a gig by French underground rock legends Magma. Over the next few years, this unlikely duo's shared affinity for visionary psychedelic music would become the foundation of not only a firm friendship, but also the most infectiously inclusive broadcasting style since the much-mourned death of John Peel.

In their weekly radio shows and a one-of-a-kind live DJ roadshow which included a legendary appearance at Glastonbury, Steve and Kavus mapped out a musical landscape of rare enchantment, where the only passport needed was a pair of open ears. No-one, least of all Davis and Torabi themselves, was expecting the 6-time former World Snooker champion and a British-Iranian underground rock musician to become one of the most trusted brands in British alternative music.

As Steve and Kavus were starting to get to grips with the challenge of their newfound status, events took a further unexpected turn. Suddenly they found themselves in a band together. And not just any band ... as two thirds of Britain's (if not the world's) leading harmonium, guitar and analogue synth power-trio (with Michael J.York of Coil)The Utopia Strong, the two friends found themselves plunging into a vortex of spontaneous compositional excitement.

How Steve and Kavus pulled this off is just one of the many questions MEDICAL GRADE MUSIC will try to answer. Part sonic memoir, part Socratic dialogue, part gonzo mission to the heart of what makes music truly psychedelic this book is the first work of joint autobiography to ever trace the evolution of a life-changing friendship through the discographies of Gentle Giant and Voivod. From the chip-shops of Plumstead to the the wildest shores of Plymouth's nineties thrash scene. it's a funny and fearless buddy movie of the soul, with a soundtrack that will make your eyes bleed.
