Jason De RonJason began playing guitar in 1987 after hearing a guitar solo by Dave Murray of Iron Maiden, and joined Paramaecium in 1992. Jason first met Andrew Tompkins in a cemetery one night in 1991. He was there with Mosh (Colin Mynard) who was a friend of his, and Paramaecium’s original guitarist. They were there to photograph the grave for the cover of the Silent Carnage demo.

Jason got to know Andrew further when he attended a Paramaecium rehearsal as they prepared for an upcoming gig with Mortification. That same night Jason also met Jayson Sherlock and the two have remained close friends ever since.When Mosh left Paramaecium in 1992, Andrew spoke to Jason about joining, and after a few meetings and songwriting sessions, they knew it would work. From there they began writing for what would become the album "Exhumed of the Earth". Jason recorded the albums "Exhumed of the Earth", "Within the Ancient Forest", the EP "Repentance" and has added some guitar to the newest Paramaecium album "Echoes from the Ground". Along with Andrew, Jason transcribed all the music from the first two Paramaecium albums for the music scores.

He has also played in the progessive metal band Soundscape and death metal band InExordium with former Paramaecium/Mortification drummer Jayson Sherlock. His influences include musicians like Larry Carlton, Chick Corea, Dave Weckl, Miles Davis, John Coltrane, Wes Montgomery, Scott Henderson, Simon Phillips and Joe Satriani to name a few.
