The Band

As a founding member, singer-songwriter, and producer, Jason Champion has been a driving force in the band's creative direction since the early 90s.  His songwriting and vocal style draw deep inspiration from the alt-rock giants of that era. With influences ranging from Toad the Wet Sprocket to Dada and Alice in Chains, Jason's music embodies the soulful, gritty essence of 90s alternative rock.  His passion for music is reflected in the music and lyrics, making each performance a raw, unforgettable experience.

Riki joined Zero Buffalo in August of 2025 after receiving a not-so-subtle ultimatum from longtime friend Jason Champion: “Join the band and beat it ... or just beat it.”  She chose wisely.   With a background in both live performance and studio work, Riki brings a dynamic, intuitive energy to the group’s rhythm section. Her drumming style is equal parts precision and pulse, anchoring the band’s sound while adding texture and movement to every song. As the newest member of Zero Buffalo, she’s already reshaping the band’s sonic landscape with her expressive playing and collaborative spirit. Riki doesn’t just keep time... she makes it count.

Warren McCallum has been the heart and soul of the bass guitar alongside Jason since 2011. As former bandmates in Autumn's Amber for an impressive 8-year run, their musical chemistry is undeniable.Warren's influences are as eclectic as they are iconic, ranging from the progressive sounds of Porcupine Tree to the classic rock of Led Zeppelin and the timeless melodies of Fleetwood Mac. His bass playing is a seamless blend of rhythm and melody, standing out as a key voice in the band's soundscape.Warren’s bass isn’t just the foundation, it’s a powerful, expressive force that deserves to be heard.
