Stefano Bonzi and Ross Lenzing have been playing music since they were little.

Both of them developed skills in different fields. Ross is a tech-genius who knows how to use any kind of equipment, while Stefano has a phenomenal natural ear and a great knowledge of music harmony and theory.


Stefano's Bio:

Stefano Bonzi is a freelance engineer born in Milan, Italy. After a career as a musician in Milan’s underground music scene, Stefano moved to the US to study sound recording at the renowned Hartt School of Music. There he acquired an extensive background in audio engineering technical skills, while expanding his musical knowledge, studying theory, and performing in ensembles. In addition to his applied and academic experiences in the field of music, Stefano has studied voice performance with some of the most distinguished teachers in the US, including Dave Kyle who has worked with Layne Staley of Alice in Chains, Liza Minnelli, and Geoff Tate of Queensryche, as well as Silvia Magnani from Milan.

Stefano started his studio career as an assistant engineer at one of the most advanced recording facilities in New England, Futura Productions in Boston, where he worked on multiple projects ranging from recording members of the Boston Symphony Orchestra to recording scores for Xbox video games.

He then brought his talent to Tapeworks Recording Studios, one of the oldest and most recognized recording facilities in Connecticut. There he became a staff engineer, specializing in recording and mixing some of the best a cappella groups in the area.

Stefano eventually moved to Los Angeles, CA, where he's now working with musicians and recording artists from all over the World.
