Pyramid Theorem

Pyramid Theorem is a 4-piece, progressive metal band from Richmond Hill, Ontario with progressive rock and heavy metal influences. Founded in the late 2000s, Pyramid Theorem includes—bassist/vocalist Christian Di Mambro, keyboardist/guitarist/vocalist Stephan Di Mambro, percussionist Vito De Francesco, and lead guitarist/vocalist Sam Ermellini.
Reminiscent of prog heroes including Rush, Ozzy, and Dream Theater, Pyramid Theorem established itself as unquenchably imaginative, determined, and skillful on its first two full-length statements (2012’s eponymous debut and 2017’s Element of Surprise) and prior EP.
As stellar as those records are, however, Pyramid Theorem’s latest collection, Beyond The Exosphere, surpasses them in every respect. Produced and engineered by Richard Chycki (Rush, Dream Theater, Aerosmith, and Pink, among others), the album sees the group setting new benchmarks for its ability to fuse impassioned and memorable songwriting with sophisticated, diverse, and virtuosic arrangements.
Released in August, 2020, Beyond The Exosphere garnered positive earned media, landed on many notable Album of the Year lists for the Metal music genre, and has been played on both mainstream and satellite radio shows.
With epic songs and crushing riffs, Pyramid Theorem executes with passion and precision, appealing to musicians and fans of great music. Their powerhouse live performance mesmerizes audiences through the interplay of guitar and bass, aggressive drums, and atmospheric, symphonic and psychedelic synthesizer work.
Pyramid Theorem has shared the stage with notable progressive metal artists including: Symphony X, Sonata Arctica, Ed Guy, Finger Eleven, Intervals, Periphery, Fates Warning, Diemonds.
