Jack Kosto  - Guitars

Jack Kosto is a metal guitarist, mixing and mastering engineer, and songwriter, who specializes in dark, theatrical music. Jack is a perfectionist when it comes to both technicality and musicality. He is also an avid lover of audio production and recording, and is passionate about creating massive, energetic, and polished recordings, from source tones to final masters. 

Jack began his musical career after learning classical viola in early elementary and middle school, and he was performing with a high school youth orchestra while only in the 6th grade. After seeing a clinic by shred guitar master Michael Angelo Batio in his hometown, Jack picked up the electric guitar, which became his first true love and primary focus. In addition to Batio’s mentorship and influence, Jack is heavily inspired by his longtime Berklee Guitar teacher Joe Stump, as well as Jeff Loomis (Arch Enemy, Nevermore), Steve Vai, Michael Amott (Arch Enemy), and Joe Satriani. Jack also draws influence from more modern bands and guitarists like Kamelot, Fleshgod Apocalypse, Nightwish, Insomium, and Ola Englund (Feared, the Haunted). Jack’s production idols include Jens Bogren, Andy Sneap, and Chris Lord-Alge. 

Jack was accepted and began his studies at the prestigious Berklee College of Music at the young age of 15, and graduated with a degree in Performance in the spring of 2016. At Berklee, he studied Jazz and Classical harmony and concepts, and he brings those to the table when writing for his main project, Seven Spires, which he co-founded with Vocalist and main songwriter, Adrienne Cowan.

In his limited spare time outside of music, Jack enjoys drinking espresso-based beverages, traveling, cooking, and relaxing at his South Carolina home.
