Connecting his talent with causes dear to his heart has been his way of giving back to the community that has saved his life. Living with a heart defect has opened his eyes to seeing the world from a unique perspective - appreciating every day of his life with passion.

He is a composer and producer whose music reflects the styles of world-renowned musicians he admires such as Oteil Burbridge, Derrick Hodge, Marcus Miller, and Stanley Clarke. Other influencers of his range from Bill Evans, Thundercat, Aaron Parks, Ben Williams, and Christian McBride. 


Mateyko's goal is to bring musician's music to everyone 

and blur the lines between the genres he loves.

Eighteen-year-old Mateyko began playing music at the age of five and fell in love with the bass at age eight. Mateyko graduated The Chicago Academy for the Arts in May of 2020 and is now attending the San Francisco Conservatory of Music on a generous scholarship to study Double Bass Performance. He currently studies with renowned NYC bassist Matt Brewer and San Francisco Symphony principal bassist Scott Pingel.


Since age 10, Mateyko has performed at over 50 charity events for Ann & Robert H. Lurie Children's Hospital of Chicago and the Children's Heart Foundation. Born with a condition called Tetralogy of Fallot, he could not engage in contact sports while growing up in a sports-heavy community. Music gave him an outlet to express himself and connect with other people. It has been an honor for him to be part of events that have raised millions of dollars for organizations that have saved his life and help improve the lives of pediatric heart patients around the world



Mateyko is an official artist for Sandberg Basses and Gruv Gear. 

His journey with Gruv Gear began at a young age. Mateyko underwent several surgeries as a child, getting a pacemaker along the way. The basses Mateyko played were too heavy for his chest and left shoulder. After visiting with specialist Dr. Randall Kertz, Mateyko was put in touch with Gruv Gear, acquiring their "Duo Strap", invented by Damian Erskein. This strap system relieved the weight of his bass and allowed him to play freely.
