It's medley time again. I managed to finish recording it just in time this year. Merry Christmas everyone!

It's that time of the year again where I take two xmas carols and smash them together in an instrumental guitar rock song I record every year. This year it's "O Little Town of Bethlehem" and "We Three Kings".

: Been working in video games ever since I graduated from university in 2003. I started out at a small tabletop & arcade games company called TAB Austria for a few years. Then moved to San Diego in 2006 to work at High Moon Studios (now part of Activision) on the Transformers and now Call Of Duty franchises. I'm mostly involved in rendering, low-level systems, and tools. But I've had my hands in almost all aspects of game dev at one point or another.
