I am a composer/producer working under several artist persona, Stefan is exploring the possibilities of musical composition for meditative environments and in support of mind-body health. After spending almost a year in doctors’ offices, acupuncture studios, yoga sessions, massage therapy, and noting just how bad some of the music being played was, I decided to try to make something better. I am trying to create new music that is relaxing and meditative in nature, but still, well, good music.

Breaking News!

Stefan has produced a new album for his alter ego, David Mash, entitled “Colors, Textures, Moods.” This is David’s first album release under his own name, and also features his other alter ego Mashine Music on synthesizers. Releasing March 13, 2023:

So who is Stefan? I am David Mash, a musician, educator, futurist and music technologist. I worked for 41 years at Berklee College of Music, where my last position was senior vice president for innovation, strategy, and technology. I have worked with the music products industry since the mid-1970s to help design and test new music technology instruments and tools and am currently working with some of the leading companies in this space to invent more powerful tools for human expression.

I also produce electronic jazz fusion music under the name Mashine Music, and my music can be found on most of the popular digital music sites, including AppleMusic, Spotify, Amazon Music, and others. I also partner with my long time friend and Berklee colleague Peter Bell in Bar of 2 Productions, to produce my music, Peter’s music, and other musicians whose music we love. Please check out my other music and projects at the websites listed here, and by the way, there is already another Stefan album already in the works, and hopefully there will be lots more to come…
