Esra Final 005x


I started my career in 1978 at Record World, a leading trade magazine and have spent my entire career in this industry.  From 1980 - 1987 I worked at two record labels; A&M in radio promotion and Arista in A&R where I had the privilege of working with the legendary Clive Davis.

In 1986, I began teaching several music business courses at various schools including Trebas Institute of Recording Arts, UCLA Extension, SAE (School for Audio Engineering) and Musicians Institute where I continue to teach today.

In 1992 I formed the Music Business Registry with my business partner Stephen Trumbull. For the last twenty years, we have published the music industries leading contact directories for personnel in A&R, Music Publishing, Film/Television Music, Music Law and Artist Management.

MUBUTV™is a blend of my passion for music as well as educating artists and others who have a strong curiosity about music, technology and the new emerging models within the business.

As an independent recording artist, I have taken the contemporarily appropriate “do-it-yourself” attitude to a whole new level; Having opened for such acts as KISS, Dave Matthews Band, Aerosmith and Kid Rock, I have worked tirelessly to introduce my original music to the masses.

Throughout my career, I have worked on both the performing and business sides of the music industry. Besides being an accomplished musician with a strong D.I.Y. work ethic, I started my own artist management company Persistent Management™ not only for my own career as an artist but also to create a vehicle for other artists to achieve their artistic vision and integrity.

My current and most ambitious project, Symbiotic Nation™ is a new entertainment company startup with a mission to reinvent the entertainment industry completely. “Think Google of the new entertainment industry.”

I’ve always had a strong passion for teaching and sharing my experience with other aspiring artists, musicians and industry professionals. As a result, I have lectured and conducted several workshops over the years with students at the Berklee School of Music in Boston as well as Musicians Institute in Los Angeles.

MUBUTV™ is the ultimate vehicle where I feel there is a genuine opportunity for artists and musicians like myself to empower themselves in order to survive as well as thrive in this new era.

Doug Probst | Co-Founder



As a proud Co-Creator and Founder of MUBUTV, I am most proud today of being a father and a husband to the two most honorable people I have on loan from God; My beautiful wife Marie and my son Joshua. From the age of 5, I have always had a passion for playing, producing, and performing music; as well as writing lyrics that have depth and meaning. and contributing that passion to other artists who want to go to the next level in their music careers.

I’ve been a working musician and recording artist my entire adult life. I’ve been fortunate to have played on numerous sessions and concert stages with some great artists including Billy Preston, Neil Young, Eric Kretz of Stone Temple Pilots and many other numerous Artists.

Currently, I am writing a book and adapting it for the stage entitled The Musings of a Narcissist. It’s a reflection of the many experiences of my life - from growing up in Boys’ Homes, being released to the streets at 17, alone, and discovering how to survive in a world I was not familiar with. Music was and is the mechanism by which I learned to cope and ultimately thrive.
