Intervals exist as the unbound and unapologetic creative expression of Aaron Marshall. The progressive guitar rock faithful revere Marshall for his virtuoso chops and melodic prowess in equal measure. His distinctive character and musical personality shine throughout the heady, catchy, and transcendent instrumental compositions found across the ever-growing catalog of Intervals albums.
The music is a window into the Toronto, Ontario, guitarist’s mind, body, and soul. Songs like “Libra,” “5-HTP,” “Belvedere,” “I’m Awake,” and “mnemonic” rank among the most popular in the genre. Metal Injection describes Intervals as “catchy-as-hell shred.” Sonic Perspectives declared the band’s fourth album, 2020’s Circadian, “strikes the perfect balance between shred, songwriting, and melody.”
A trio of gifted touring and recording musicians surround Marshall as they collectively share Intervals’ songs with the world: drummer Nathan Bulla, bassist Jacob Mansky, and guitarist Travis LeVrier. They consistently stun audiences, including on celebrated treks with Spiritbox, TesseracT, Animals As Leaders, Polyphia, Periphery, Protest The Hero, and Between The Buried And Me.
The earliest Intervals offerings, including two EPs and 2014’s full-length debut, A Voice Within (the sole album with lead vocals), were decidedly heavy and aggressive. Heralded by MetalSucks as “fantastic” and “lacking virtually nothing,” 2015’s The Shape of Colour ventured in a new direction. Intervals' fourth album was appropriately titled The Way Forward. “Employing many of the same techniques as technical progressive metal but in a major-key, upbeat framework has been Intervals’ calling card,” wrote Metal Hammer. “[The Way Forward] is a purer distillation of [Marshall’s] aim.”
Circadian marked Intervals’ first collaboration with Sam Guiana (Silverstein, Neck Deep, Holding Absence). memory palace brilliantly celebrates the best of Intervals’ past, present, and future. The album is diverse, uplifting, and crushingly heavy. Also produced by Guaiana, memory palace includes collaborations with KOAN Sound (“neurogenesis”), J3PO (“galaxy brain”), and OBLVYN (“lacuna”).
Fiercely independent and precision-focused but never lacking in uplifting vibe and fun, Intervals continues to grow from Marshall’s strong roots in authenticity, instinct, and trusting one’s gut.
