Carlos Costa


Carlos began playing music at age 7, when he started taking accordion lessons at the Milton Mann Studio in Culver City, California. A multi-instrumentalist, his primary and favorite instrument is definitely the bass guitar. Carlos earned letters in Concert as well as Marching Band while in High School and was offered scholarships to Berklee School of Music and USC. He ultimately chose to study composition at the California Institute of Arts in Valencia, California. With Natural Science, Carlos plays the “Geddy” role; taking on Vocals, Bass and Keyboard duties. As a lifelong Rush fan, Carlos feels privileged to have the chance to pay tribute to his idols. Playing Rush’s music has always been fun, but playing it live for other fans is really a special feeling. Carlos hopes to continue playing and growing with Natural Science for years to come.

Greg Russell

Greg the happy drummer

Greg started playing drums at the age of 13, but was banging on things since he was born. Playing throughout high school and college, where Greg played drums, lead guitar and sang lead vocals, his love for music continued and developed along with his professional animation career. Through his work in that field he was fortunate enough to become friends with Neil Peart, producing videos for Neil and Rush during for their live concert performances. After Neil’s passing, Greg decided to really learn some of his favorite Rush tunes, and was discovered by the Natural Scientists…the rest is history (as it develops!). 

In addition to his role behind the kit, Greg composes original music, and has written theme and background music for several TV shows and feature film companies.

Zephry Lyne


Zephry has been playing guitar since he was 13, but his musical life started long before that. From starting on the violin back in 2004, to adding trumpet in middle school and piano and euphonium in high school. After high school, Zephry played in multiple original bands, and attended and graduated with an AA in music/performance and technology from Clackamas Community College in Oregon City, then moved to L.A. in September 2018 to attend Musicians Institute in Hollywood. In addition to playing guitar with Natural Science, Zephry is involved in many other musical projects from various session gigs, to playing in his original band “Jane Doe” which is about to release their second album on all major streaming platforms. Zephry also acquired a last minute 3 week midwest tour back in May 2022 filling in on lead guitar for Oakland indie band “Bad Camper” with only a one day notice to prepare. Zephry is a relatively new fan of Rush after seeing them in Portland Oregon in 2015 on the R40 tour. He’s been hooked ever since and absolutely loves performing the music of Rush with the other two brilliant musicians in the band and wants to carry on his musical passion in Natural Science as well as his other music projects!
