About my Music

My Goal

My goal as a bassist and composer is to find where the essence of the music lies, no matter the complexity of it,  and bring it forward so its available to everyone. I truly believe that no art form should be isolated from the others. Music should relate to images, stories and emotions.

To become better with my instrument and broader in my musical knowledge, every day.

My Journey

I am a doublebassist cur­rently liv­ing in Lis­bon, try­ing to learn and play as much as I can. I’m teach­ing dou­ble­bass at the “Villas-Boas Jazz School” from the Hot Clube de Por­tu­gal and just released my second album as a leader called "Truth Has To Be Given In Riddles".

The first one is called "Whatever It Is You're seeking, Won't Come In The Form You're Expecting"

I studied doublebass at the Conservatory of Amsterdam and graduated in 2010. Had some great teachers there and had the opportunity to study privately with great musicians such as John Clayton, Reuben Rogers, Larry Grenadier, Clemens Van Der Feen and Alejandro Erlich-Oliva. I won a couple of prizes and had the oppor­tu­nity to play at some of the biggest venues and festivals around the world.
