Instrumental music is a universal language. It can tell a story, change a mood, stimulate the intellect and create pictures in the mind. And all without a single word being uttered.

“Even if I had a particular word or words in mind, I would not tell anyone, because the same word means different things to different people. People usually complain that (instrumental) music is so ambiguous, while words are understood by everyone. But for me it is exactly the opposite...what the music I love expresses to me are thoughts not too indefinite for words, but rather too definite.” - Felix Mendelssohn

“I realised a long time ago that instrumental music speaks a lot more clearly than English, Spanish, Yiddish, Swahili, any other language. Pure melody goes outside time.” - Carlos Santana

My singular passion is to compose and produce modern hybrid chamber music, a genre crafted for a mixed acoustic and electronic ensemble from classical, jazz, pop and electronica influences.

On this site you'll find a mixture of my own work and some arrangements I've produced of classic, well known instrumental pieces. I sincerely hope they bring pleasure to your life.

My new track Bobblehead is now released here and will be available for sale at CD Baby, Amazon, Google and iTunes in coming days. This track has a deliberate retro funk blues edge to it (and features my beautiful new Fender Nashville Telecaster guitar!). It has been described as "the hideous love child of Eric Clapton and Quincy Jones" :-), I hope you enjoy it, and thanks as always for your continued support and kind words. RCS
