    20 BIG ONES

    Not counting some early moonlighting, Gravity Music officially came to be on January 1, 1996.  Here we are 20 years later, better than ever, still loving the work, still reaching to be better every year.  Congrats to Gravity!

  • 1950s radio


    Currently in the shop: a game score for a Chinese game dev we can't tell you anything about, a jingle package for Sonoma County's largest car dealer, meetings with a kick-ass Santa Rosa bakery, and Jim's first-ever collection of his own songs.


You’ve found the corner where art and entertainment meet: the address for great commercial music and audio design in Sonoma County. Smart, focused ad music that goes in your ear and sticks there. Instrumental scoring that runs the gamut from documentary film to video games. Inventive sound design that “reads.” And radio that’s surgically produced with a musician’s sense of time and balance. Thanks for visiting, please take some time with the samples, and give me a call: I’m eager to put my skills to work for you.
