Si has worked for Coast to Coast for longer than anyone can remember. Put him behind a mixer and he'll just get on with it. Any genre, from Gareth Gates to experimental jazz, hard rock to world music.
A memorable quote from Simon involved a member of a particularly discerning audience congratulating him on the quality of his mix. The music was a quite ermm... challenging modern classical orchestra and upon being asked how long he had been mixing orchestral works Simon replied "About two days."
Simon has just completed a 6 week UK & Ireland tour with LA metal band My Ruin.
The ever handy baby-names-world.com usefully informs us that the name Simon means "he who hears", so he must have been destined to this role.
